Set of 16 PROFORM Nickel Plated Grade 8 M8 X 1.181” Wedge Locking Header Bolts.

This set of 16 PROFORM Nickel Plated Grade 8 Wedge Locking Header Bolts are direct-fit replacements for 4.6L and 5.4L Mustangs. Each bolt is made from grade 8 steel and is made to the original M8 X 1.181” thread pitch and measurements. Each bolt features a hex head design, making them compatible with common ratcheting bits. When properly torqued to 28+ ft-lbs, the washer’s super-hardened external teeth bite into and grip the bottom of the bolt head and the top surface of the header.

This keeps them from backing out or loosening while driving. After being self-locked in this manner, any bolt-loosening rotation is blocked by a wedge-locking action created by the washers interfacing, matching cams. The set is sold as a set of 16, so you can get the job done in one go.
