Place Bolts

Product Note

UPDATE: Revision H has been approved. This new revision fixes the part number and dimensional errors present in Revision G, and reestablishes continuity with the part numbers in Revision F. Revision H also provides zinc-nickel plating as an alternative to cadmium. Wilson-Garner is happy to quote parts to this new revision.

We have become aware of some part number errors and omissions in the new MS35764 Revision G. Some part numbers have different dimensions than their Revision F counterparts, and some part numbers found in Revision F are omitted entirely from Revision G. Please double check to ensure that the part number listed in Revision G is actually the part that you want. If you cannot find the part number in Revision G, we are happy to quote to Revision F.

Wilson-Garner Self-Locking Place Bolts

Vibration causes fasteners to loosen over time, a process that’s not only dangerous but also costly. Every time someone has to check and re-tighten bolts, you lose time and money. Wilson-Garner’s American-made, self-locking place bolts save both by resisting vibrational loosening up to 7x better than conventional hex head cap screws.

Ideal for any application where vibration threatens to loosen traditional bolts or screws, our place bolts are used in military and commercial engineering standards for applications like flywheels, cylinder heads, ring gears, flexplates, compressor mountings, transmission covers, and even oil rig mud pumps. No matter your application, Wilson-Garner’s self-locking, free-spinning bolts are manufactured to your blueprints or specifications, in any quantity you need.

Product Features:
Cold-Formed | One Piece | All Metal | Self Locking | Free Spinning | Reusable | American-Made
