Double End-Threaded High Strength Studs

Our Standard OEM and Custom-Manufactured double end studs are fasteners that are threaded at each end with an unthreaded portion at the center. Also called connecting rods or double ended studs, they are typically used to join together female-threaded components that don’t require a full thread or items that have varying thread sizes.

While our stock inventory primarily includes double end studs that from 5/16″ to 7/8″ in diameter, we can also design and custom-fabricate specialized double end threaded studs that meet your specific needs and length requirements.

Our full range of sizes, shapes, and thread configurations is available upon request.

Double End Threaded Bolts - Rely On Our Strength & Precision

Our double end studs offer strength levels ranging from 180 ksi to 380 ksi, and we’re experienced in manufacturing studs to exact tolerances.

Premium studs utilize a bottoming boss to aid in a more uniform stress load distribution and repeatable clamp load. Need help with your solution? Call (315) 924-3888 today.

The 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

If you can draw it, dream it, or describe it, we can make it.

As a custom fastener manufacturer, our facility is able to either adhere to strict OEM specifications or fabricate custom-engineered double end bolts based on your schematics.

The 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.

Modern Facility Layout

We can accommodate expedited requests, low/high volume runs, and adjust to varying timelines.

Constant Quality Control

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