The 7/16-20 x .875 12pt Bolt w/LH Threads from JESEL is a precision fastener designed for various applications, particularly in motorsports and engine assembly. This left-hand threaded bolt is essential in scenarios where standard right-hand threads may loosen due to rotational forces or vibrations. Builders and enthusiasts seeking reliable fastening solutions will find this bolt beneficial in both competitive and street performance settings.

With a diameter of 7/16 inch and a thread pitch of 20 TPI, this 12-point bolt offers a larger grip surface area compared to standard six-point designs. This design helps distribute clamping loads evenly, minimizing the risk of rounding during installation. JESEL's stringent manufacturing tolerances ensure consistent head geometry and thread runout, which are crucial for maintaining valve train geometry and cylinder head sealing in high-RPM applications.

Engine builders and serious enthusiasts upgrading to performance valve train systems will find this bolt indispensable for both small-block and big-block builds. It is important to verify compatibility with your specific engine platform and valve train architecture, particularly regarding bore diameter and thread pitch.
