PROFORM Releases Grade 8 Wedge-Locking Collector Bolts

New from PROFORM – the Grade 8 Wedge-Locking Collector Bolts. These bolts feature new technology resist vibration loosening while being easy to use and reusable. See more details below.

Official Release:

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 untightened with a normal wrench, lubricated, and reused.

Features:

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