8mm (5/16") Aluminum Conical Washer
These low-profile conical aluminum washers fit 5/16" or 8mm countersunk screws (not included). They are ideal for kart seat attachment hardware because the shallow (approx. 42°) angle of the shoulder minimizes pressure points. Hard anodized finish available in Clear, Black, Blue, Gold, or Red.
