M10 M16 Stainless Steel Square Washer SS304 SS316 A2 A4-80 Square Metal Washers

Square shaped shims and round shims are common fasteners used for connecting gaps and distributing stress between bolts, nuts, and connecting parts. They help reduce friction, limit deformation, transfer pressure, and prevent leaks.

• Shape: Square shims have equal side lengths with 90-degree angles; round shims have uniform circumferential edges
• Applications: Square shims are ideal for square structural connections like angles, I-beams, and rails; round shims suit wider applications
• Materials: Both use various metals (steel, copper, aluminum) and non-metals (rubber, silicone) depending on working conditions
• Stress Distribution: Round shims distribute stress more evenly; square shims may concentrate force at corners
• Torque Control: Round shims allow easier torque control during installation

Wire Cutting Process: Uses energized metal wire to melt material without direct contact. Ideal for hard metals and small-lot production with no burrs.

Laser Processing: Uses laser beam heat energy for precise cutting of complex shapes. Best for materials 0.05 to 2mm thick and small production runs.

• Clean with mild detergents and soft cloths
• Avoid acidic/alkaline cleaners to prevent surface damage
• Use stainless steel stain removers for stubborn dirt
• Alcohol or vinegar can be effective cleaners
