Countersunk bolts is a non-metallic fastener designed specifically for flat surfaces. Its precisely conical head mates with the countersunk hole for a perfectly flush installation. The tapered head creates a seamless transition with the workpiece surface, eliminating any obstructions. The precise 90° taper ensures even pressure distribution after tightening, effectively extending the fatigue life of the joint.
