SAE Flat Washers feature a smaller outside diameter than USS flat washers. They are made with tighter tolerances to meet strict performance requirements. Available in various zinc coating options, with material options that include:
- Low Carbon Steel
- Medium Carbon Steel
- Alloy
- Aluminum
Heavy SAE Flat Washers
Heavy SAE Flat Washers are designed with added thickness and strength for use in heavy-duty applications. They are made for securing bolts in structural or heavy-duty assemblies. Heavy SAE flat washers are made from medium carbon steel and feature a yellow zinc coating.
Fender Washers
Fender Washers have a wide outer diameter to spread loads over a larger surface. Commonly used in sheet metal, insulation, or where holes are oversized or irregular. Material options for fender washers include steel and Stainless Steel (18-8 and 316).
F436 Structural Flat Washers
F436 Structural Flat Washers for use with structural bolts, F436 washers meet ASTM standards. They are often used in steel construction and load-bearing connections. They are made from a high-strength medium carbon steel and are available with a plain finish or hot-dip galvanized coating.
Lock Washers
Split Lock Washers
Split lock washers have a literal “split” design that allows the washer to dig into surfaces when fastened. These washers resist loosening and help maintain integrity under vibration. Material options for split lock washers include:
- Zinc-Plated Steel
- Stainless Steel (18-8 and 316)
- Medium Carbon Steel
- Aluminum
- Silicon Bronze
- Alloy
Hi-Collar Lock Washers
Hi-collar lock washers are designed for use with socket head cap screws and feature a smaller outer diameter. They provide locking action in applications with limited space. Material options include Medium Carbon Steel and 18-8 Stainless Steel options.
Internal & External Tooth Lock Washers
External Tooth Lock Washers feature external teeth that bite into the mating surface, increasing holding power and preventing fastener rotation. They are typically used for larger head screws.
Internal Tooth Lock Washers feature teeth on the inside edge, ideal for smaller fastener heads. We also distribute
Internal/External Lock Washers that feature teeth on both the inside and outside diameter to maximize holding strength in high-vibration applications. Material options include:
- Steel
- Stainless Steel (18-8 and 316)
- Silicon Bronze
Specialty and Application-Specific Washers
Belleville Disc Spring Washers (Stainless)
Belleville Washers are conical-shaped springs that apply preload and maintain tension in bolted joints. Often used in dynamic or thermal cycling applications to compensate for relaxation or expansion. Material options include steel or 18-8 Stainless Steel.
Beveled Washers
Beveled Washers are angled to compensate for sloped surfaces in structural steel applications. They help maintain proper bearing and load alignment. Beveled washers are made from steel and are available with a plain finish or a hot-dipped galvanized coating.
Bonded Sealing Washers
Bonded Sealing Washers combine a metal backing with a rubber sealing element to prevent fluid or gas leaks. Common in plumbing, hydraulic, or electrical applications. Available in steel or stainless steel.
Countersunk Finishing Washers
Countersunk Finishing Washers are designed for use with flat or oval-head screws. They provide a clean finished appearance and are often used in decorative or visible applications. Material options for Countersunk Finishing Washers include:
- Steel
- 18-8 Stainless Steel
- Brass
The Primary Benefits of Washers
Washers are designed to help distribute loads while protecting surfaces. Some styles of washers, like lock washers, are designed to create a stronger grip that resists loosening caused by vibration. Other washers can create a seal that keeps moisture out. With numerous types available, washers address a wide range of fastening challenges.
