Brass machine screw nuts for general fastening

This pack supplies ninety-six #4-40 brass hex nuts designed to mate with matching machine screws or bolts. The brass construction resists corrosion and provides good electrical conductivity for grounding or terminal work. Buyers who need stainless steel, nylon or metric threads will not find those options here.

Ready to use with standard #4-40 threads

Each nut fits the common #4-40 unified coarse thread pitch used in electrical boxes, terminal strips and small mechanical assemblies. No special tools are required beyond a standard hex driver or wrench. The bulk quantity reduces re-order frequency for maintenance kits or production bins.

Consistent dimensions support repeated assembly

Manufactured to standard tolerances, the nuts thread smoothly and hold clamping force through multiple install-remove cycles. Brass resists galling better than steel on soft materials, helping maintain joint integrity over time. The product carries California Proposition 65 warnings for cancer and reproductive-harm substances.
