Brighton-best 332035 Hex Machine Screw Nut 4-40 Pack of 100

Product Description

The BRIGHTON-BEST 332035 is a 4-40 hex machine screw nut designed for use with 4-40 threaded fasteners in light-duty mechanical and electrical assemblies. Manufactured from low carbon steel with a plain (uncoated) finish, this nut provides reliable thread engagement in applications where corrosion resistance is not a primary requirement. The 4-40 thread designation indicates a number 4 screw diameter with 40 threads per inch, a common size in electrical panel work, electronics enclosures, and instrument assemblies. Each package contains 100 nuts, making it a practical choice for technicians who need to stock or replenish hardware inventory.

These hex machine screw nuts are used across a range of light mechanical and electrical trade applications including HVAC control panel assembly, electrical junction box work, instrumentation mounting, and general equipment fabrication. The 4-40 thread size is frequently encountered in low-voltage control wiring enclosures and electronic equipment found in residential and commercial systems. Electricians, HVAC technicians, and equipment assemblers commonly use this size when securing small machine screws in threaded holes or with a mating screw and nut configuration.

Installation Notes

Installation is performed by hand or with a standard hex nut driver or wrench sized for the 4-40 hex nut profile. Ensure the mating screw thread is 4-40 before installation to avoid cross-threading. De-energize any electrical equipment before performing fastener work inside panels or enclosures. Follow applicable NEC or equipment manufacturer guidelines when working inside energized enclosures.
