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.
