Difference Between AF Shims

Shims are thin pieces of material used to fill gaps, align components, or provide support in various assembly applications. Shims offer different material compositions, properties, and applications. Allfasteners offers aluminum, metal, and plastic shims with various benefits. 

• Aluminum Shims:

• Lightweight material, making the shims easy to transport
• Corrosion resistant with their protective oxide layer 
• They are strong and support heavy loads 
• A great conductor of heat and electricity 
• Best used in precise alignment of machinery and equipment 

• Metal (Steel) Shims:

• Steel shims are well known for their strength and load-bearing capacity
• Resistant to wear and tear
• Coated in galvanized to enhance corrosion resistance 
• Most steel shims are magnetic
• Best used in heavy machinery, industrial equipment, and structural applications

• Plastic Shims:

• Made with polyethylene or polypropylene, making them lightweight 
• Since plastics do not corrode, they are suitable for wet environments 
• They provide electrical and thermal insulation 
• They can resist chemicals and moisture 
• Best used for plumbing, HVAC, window and door installation, and electrical applications
