Stainless steel shim stock offers excellent corrosion resistance, making it suitable for use in high-corrosion environments. Furthermore, its malleability makes it useful in leveling surfaces or filling gaps between them.

Machine adjustment is key to productivity. PBP manufactures shims with precise thickness tolerances that are clearly labeled with material type, thickness tolerances and lot numbers to provide full traceability of each unit.

Stainless Steel

Stainless steel shim stock is an extremely versatile material, offering the ideal combination of strength, hardness, and corrosion resistance. Due to chromium’s exceptional level of corrosion resistance that makes these shims suitable for harsh outdoor environments and marine applications alike. Thus making Stainless Steel Shims the ideal choice when tolerances and durability are key considerations in any application.

Shims are an effective solution for filling any gaps that occur between machined components. This can significantly lower machining costs by decreasing tolerance requirements between them, improving process efficiencies, and increasing throughput – something shims are widely utilized for in many industries.

Shims have long been used in automotive manufacturing to protect brake deterioration and premature wear, but they can also be found useful in aerospace, construction and other precision-oriented industries where precision is vital. Utilizing stainless steel shims can reduce alignment adjustments required by traditional methods resulting in faster production times with reduced maintenance expenses.

Process for using shims may differ depending on the industry, but in general the procedure entails measuring the thickness of gaps using feeler gages of increasing sizes to identify their width and determine their corresponding shim size. Once this information has been acquired, stainless steel shim stock must then be wedged in to fill them to achieve a tight fit; typically being slightly thicker than necessary will ensure this happens efficiently.

Stainless shim stock spacers differ significantly from aluminum spacers in that they are highly durable and resistant to corrosion, making them much simpler and longer-lived options than their aluminum counterparts. Cleaning them and maintaining them should also be easier – an added advantage!

Precision Brand stainless steel shim stock comes in various sizes and thicknesses to meet every industrial need. This material is especially beneficial in tool and die set up, alignment, machine assembly, repair work and alignment services for new machines. In oil & gas applications such as absorbing tolerance accumulation in pumps and motors or acting as thrust washers; additionally it’s perfect for short run or prototype projects where accuracy and economy are critical factors.


Brass shim sheet is an extremely reliable material that makes an ideal material for various applications. Used to adjust mating parts’ fits or reduce friction between two surfaces, brass shim stock comes in various sizes and thicknesses to meet every application imaginable – even round shapes for use on curves or angles!

Brass is an alloy made up of copper and zinc with many unique properties, such as its corrosion-resistance. Due to this feature, brass has become popular among metalworkers for metalworking projects; additionally it can withstand impacts and vibrations typical in industrial settings without showing signs of fatigue or breaking. Furthermore, brass is easily recyclable making it an eco-friendly material choice.

Shims are essential components in mechanical assemblies, filling gaps between parts to ensure they work seamlessly. Misalignment between components can cause reduced performance and increased wear-and-tear, so brass shims provide an affordable yet effective way of avoiding these issues.

This shim stock roll is constructed of half hard, cold rolled CDA 260 alloy brass for optimal forming qualities and versatility. Light drawing, blanking or stamping may be done to achieve maximum use out of this roll; furthermore it is rust resistant, offering repeated use in various environments – perfect for applications including adjusting valve spring pressure adjusting thermal insulation support equipment support etc.

As well as its durability, this shim is also abrasion-resistant and can be cut with scissors or sheet metal shears without deforming or bending it. Cleaning this item is straightforward – although any residue from cleaning chemicals must be rinsed well to remove all trace particles – any left behind can react with copper to form green-blue compounds that etch or pit brass surfaces, potentially producing greenish compounds with unintended results.

Another advantage of the Copper Shim is its antimicrobial properties. Copper helps fight off pathogens such as bacteria and pathogens – especially helpful in environments that demand sterility like healthcare or food applications.


Copper shims are an indispensable industrial part, often used to align machinery parts. Additionally, they seal gaps between surfaces. Their long lifespan means they can withstand extreme temperatures without cracking or losing shape, while being excellent heat/electrical conductors – making copper the ideal material choice for electronics use.

Copper sheets come in various alloy forms that give them distinctive physical properties, including bronzes, brasses, nickel silvers and copper-nickel alloys. When selecting the metal best suited to your specific application based on temperature range alone, copper is often an ideal candidate as its relatively low melting point makes it easier to work with and its strength remains intact at higher temperatures.

Copper stands out among metals due to its natural resistance to corrosion and can withstand both high- and low-temperature environments, making it suitable for industrial and household applications alike. Copper’s natural anticorrosive qualities also make it an excellent choice for electrical, plumbing, mechanical applications and more.

Copper’s journey toward becoming a shim sheet begins with mining. Mined copper typically exists alongside other minerals and materials and must first be separated before it can be utilized for other uses. Once separated, it must then be put through an immense furnace to eliminate these impurities and extract pure copper for use in other products.

Copper wire is then rolled into large rolls for manufacturing and industrial uses, such as electrical wiring or the creation of other forms of equipment. These large rolls provide an invaluable source of copper.

Copper shims are immensely useful industrial tools. Common applications for copper shims include machine alignment and assembly, repairs to existing machines, filling small gaps between parts to reduce frictional forces that would otherwise cause maintenance or replacement needs, filling small gaps between components to fill small spaces between components or even helping ensure water leakage does not occur.


Aluminum shim sheets are an ideal lightweight option, while remaining corrosion-resistant and very strong. Furthermore, aluminum can easily be formed into various shim shapes for increased versatility as well as being suitable for high temperature environments.

Shims offer many advantages when it comes to tolerance stack-ups, including being faster at meeting various close tolerances quickly – saving both money and space!

Laminated shims are frequently employed in complex mechanical assemblies to compensate for manufacturing tolerances and provide a precise fit between parts. Constructed of multiple materials – typically brass, carbon steel and stainless steel – laminated shims can come in various thicknesses and be manufactured either fully laminated or from 1/2 solid stock, depending on your application and requirements.

Benefits of using shims for assembly purposes include reduced assembly costs, improved productivity and accuracy, as well as easier lamination. Laminated shims can also be cut to size quickly for quick installation in curved areas; additionally laminated shims may even reduce noise levels in equipment.

Selecting the ideal material for shims will have an enormous effect on their performance and longevity. Heavy machinery may need something stronger while flexible lightweight shims may work best with less demanding machinery. You should also keep in mind your working environment; for instance, if dealing with harsh chemicals or acids you might opt for stainless steel or nickel; aluminum or copper would offer more durability options.

SPIROL stocks standard aluminum alloys from thicknesses 0.05mm to 3mm (.002″ to.125″). They make an ideal choice for industrial, marine and commercial applications that require corrosion resistance while being easy to clean with most common cleaning agents and non-magnetic for machine tools and equipment applications.
