Allen Lock Header Stud System

This kit come with high tensile studs, heat treated nuts and precision locking washers, everything to keep your headers tight and not leak. Headers that form a leak can lose at least 15 hp per header side. The kits are easy to install and keep tight. Screw the studs in your head with Allen wrench, hang your gaskets on studs, then install header. The special 12 point (Double Hex) socket has 12 driving points for easier hex key engagement. With this special vibration-free nut, you are able to tighten your header from approximately 50% more positions than you can with an open end wrench. A stud/nut combination is always better to use than a bolt. This system can withstand at least 50lbs of torque. GM OEM recommends header bolts torque to 35lbs.

12 Quanity - Kit Includes: 3/8"-16 x 1-1/2" socket studs, 12 pt socket, 3/8" nuts, 3/8" precision split lock washer.
