Fastener Locknut - Flanged - 3/8""-16

Fastener Locknut - Flanged - 3/8""-16

This 3/8"-16 flanged locknut is a heavy-duty fastener designed for general use across concrete mixer trucks, including McNeilus, Terex, and Con-Tech models. The integrated flange eliminates the need for a separate flat washer by distributing the load over a wider surface area, which prevents damage to the equipment and ensures a tighter hold. Engineered to withstand the intense vibrations of daily mixer operation, the locking design prevents the nut from backing off the bolt or stud. It is an essential replacement hardware piece for maintenance and repairs on chutes, brackets, and structural mounts where secure, vibration-resistant fastening is required.

Key Features

• Integrated flange design distributes clamping load and eliminates the need for a separate washer
