Hella Solid Spherical Washer Made From Low Carbon Steel With A Tough Black Oxide Coating Designed For 3 8 Inch Screws And Studs Offering A Spacious 13 32 Center Opening Plus A Hefty 7 8 Flange For That Trusty Hold Anywhere

Premium spherical washer single pack for garage build outs
✔️ Low carbon steel spherical washer fits 3/8 inch hardware perfectly

This heavy duty ball bearing style disc distributes compressive loads across fastened joints. The curved underside lets bolts tilt naturally when mating surfaces are not perfectly flush. Builders and auto technicians mount these on suspension arms, engine brackets, and trailer hitches to stop cross threading and keep tension locked during road vibrations.

✅ Corrosion resistant black oxide coating shields metal surfaces
✅ 3/8 inch bore size accepts standard grade five and grade eight studs
✅ 13/32 inch hole diameter prevents contact with threaded sections
✅ 7/8 inch flange edge reduces surface stress concentration points
✅ Quarter inch wall thickness handles repeated torque cycles
✅ Plus minus 0.010 inch machining tolerance keeps alignment precise
✅ Point four fourteen inch cup depth matches typical pitch angles
✅ Rockwell B49 surface hardness resists deformation under pressure
✅ Single unit arrives with pre paired male and female half set

💡 What are spherical washers used for in automotive suspension setups?
This handy upgrade resolves alignment headaches by letting fasteners pivot freely while maintaining clamp force. Technicians install the domed disc between a bolt head and metal bracket to equalize pressure on warped chassis components. Swapping out cracked flat washers with a precision cup shaped washer keeps your steering linkage solid under rough terrain.
- Dome profile bridges gap variations without requiring adjustable spacers
- Transmits tensile loads straight through the bolt axis to prevent bending
- Prevents galling on zinc plated threads during frequent maintenance cycles
