Wedge-Locking Exhaust Collector Bolts

Loose collector bolts end here!

PROFORM's Wedge-locking bolts offer a simple locking bolt that doesn't require any special tools, adhesive, or small parts…just tighten them up and you're done!

One less thing to come loose is enough of a reason to check out these simple locking bolts! Each PROFORM Grade 8 Collector Bolt and Nut combo includes two pairs of special locking washers. When the combo is torqued to 28+ ft-lbs, the washers’ super-hardened external teeth bite into and grip the bottom of the bolt head and the top surface of the flange.

    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. It’s an uphill climb: vibration that might ordinarily loosen the bolt actually increases the wedge-locking tension, securing the bolt even more. Because this simple wedge-locking method uses tension instead of friction, contact with oil actually facilitates the wedge effect. PROFORM Collector Bolts can be un-tightened with a normal wrench, lubricated, and reused.

    • Resists vibrating loose
    • Super-hard cam-locking washers
    • No little clips or retainers to handle
    • Oil actually improves performance
