Value Collection C86315 Serrated Flange Nut 3/8-16 50 Pack

Product Description

The VALUE COLLECTION C86315 is a serrated flange nut with a 3/8-16 UNC thread size, designed to provide secure clamping and vibration resistance without a separate washer. The integrated serrated flange distributes load across a wider bearing surface while the teeth bite into the mating material to resist loosening. Made from Grade 2 steel with a zinc-plated finish, these nuts are suited for general mechanical and structural fastening in HVAC, plumbing, electrical, and equipment assembly applications. Each pack contains 50 nuts. Licensed tradespeople and maintenance technicians reach for this style of nut when a standard hex nut is not sufficient to hold under vibration or dynamic load.

These serrated flange nuts are appropriate for light to medium-duty fastening tasks in residential and commercial mechanical systems. Typical uses include equipment panel fastening, bracket mounting, motor and fan assembly, and general mechanical connections where vibration is a concern. The zinc-plated finish provides basic corrosion resistance suitable for indoor and sheltered environments. The pack quantity of 50 makes this item practical for service trucks and shop stock.

Designed as a general-purpose 3/8-16 UNC serrated flange nut suitable for standard inch-system threaded fastener applications in mechanical, HVAC, electrical, and plumbing equipment assemblies.

Installation Notes

Installation of flange nuts is typically performed by licensed HVAC technicians, electricians, plumbers, or qualified maintenance personnel. Always de-energize equipment and relieve any pressure or tension in the system before replacing or tightening fasteners. Use the appropriate wrench size matched to the width-across-flats dimension to avoid rounding the nut. Do not reuse serrated flange nuts in critical joints where the serrations may have already deformed the mating surface.
