The Butler OptiTorque Difference

  • Our fastener studs and fastener bolts are rolled after heat treatment to retain the compressive stresses necessary to increase fastener fatigue and durability.

  • Our flanged fastener bolts, flange nuts, and thru-hardened ground washers are all engineered to maximize joint integrity, while achieving the proper frictional area to resist both thermal and vibration loss of joint load.

  • OptiTorque fastener studs and fastener bolts are produced from oversized raw material to remove surface impurities throughout the manufacturing process ensuring the surface condition is in a pure & prime state during critical production stages like heat treating and thread rolling

The Butler OptiTorque Advantage

Fastener Precision

Our fasteners are straightened prior to centerless grinding to maintain concentricity and roundness.

Strength & Durability

Our ultra-high strength, high fatigue fasteners can have up to 8x more stretch area than OEM applications.

High Grade Materials

We utilize only domestic melted steel from specific production lots to ensure that the cleanest and most uniform grain structures are used in production.

Bake Out / Load Testing

Fasteners produced for certain critical applications go through additional test procedures. 

Constant Quality Control

Quality is measured throughout each process, both non-destructive and destructive mechanical tests are performed on each production batch.
