Heavy Duty Six Angle Bolts Need Washer?

- Oct 12, 2017 -

Is it necessary to use a washer when connecting heavy six angle bolts?

The main function of heavy six angle bolts is to avoid bolt scratching and reduce bending force. Is it necessary to use the washer or the specifications of the heavy six angle bolts?. Bolt hole is too large when they should add a washer to increase the contact area, another bolt mounting hole is close clearance can not add another washer, you can refer to the gasket standard, general gasket hole than the bolt diameter too large, so look under DW than in washer hole is not much. Especially when installing DW spring washer lug directly expanded washer, did not play a good role. Personal advice bolt assembly hole should not be too big, do not install gasket
