Summit Racing™ Split Lock Bolt Kits

4.48 out of 5 stars 33 Customer Reviews

Summit Racing™ split lock bolt kits put a new twist on the theory of mechanical locking fasteners. These innovative bolts use a locking set pin built into the bolt itself—and when tightened, the set pin expands the bolt threads against the thread wall. This, in turn, provides a locking system without having to use any additional wires, locking compounds, or lock washers. To remove the split lock bolts, simply loosen the set pin and back out the fastener. They are available in a variety of thread sizes, for engine applications from the 1950s and up.
