Crouch Sales has supplied fasteners for electric utility infrastructure for decades. We know that substations run on tight tolerances and zero margin for error, and the hardware and fasteners holding those connections together matters just as much as the equipment itself. When a bolted joint loosens or a washer fails to compensate for thermal cycling, the results can be catastrophic.

That’s why we stock the fasteners electric utility contractors and substation crews rely on. Our substation fastener inventory includes:

• Belleville Disc Spring Washers
• Flat Washers USS
• Hex Nuts
• F436 Structural Flat Washers
• Lock Washers
• Hex Cap Screws & Bolts

At Crouch Sales, our customers working in the electrical utility sector get a “Service First” experience, every time. Our Sales Staff actually knows fasteners, carrying over 100 years of combined experience with Crouch Sales. Our team knows our warehouse inventory through-and-through, so you can get accurate technical questions right away.

Fasteners for Electric Utility Infrastructure Built to Handle the Job

Substations and switchyards aren’t typical fastener applications. These environments require fastening hardware manufactured to handle constant vibration, sharp temperature swings, and sustained exposure to outdoor elements. Whether you’re maintaining an existing substation or building a new one, Crouch Sales carries the substation fasteners to keep your project moving.

Belleville Washers for Electrical Substation Applications

We maintain a massive stock of Belleville disc spring washers. These specialty washers are manufactured for the most demanding electrical substation applications. Belleville disc spring washers are designed to:

• Maintain bolt preload: Standard flat washers can't compensate for the small amount of material relaxation that happens after a joint is torqued down. Belleville washers can. They apply continuous spring force to the joint, which keeps preload consistent even as the connection settles. The reason that’s important: a loosening bolt on an electrical connection increases resistance at the joint, and resistance generates heat. That heat buildup creates a hot spot, and a hot spot on live electrical equipment can be catastrophic.
• Compensation for Thermal Expansion and Vibration: Substation hardware faces constant vibration caused by transformers, as well as thermal cycling as equipment heats and cools throughout the day. Belleville washers flex to absorb vibration and are designed to withstand temperature swings.
• Made for Outdoor Exposure: We offer Belleville washers made from stainless steel, so they withstand the harsh outdoor conditions that substations experience year-round.
