Value Collection KP82430 Button Cap Screw M3x0.50 16mm 25-pack

Product Description

The VALUE COLLECTION KP82430 is an M3x0.50 button socket cap screw designed for metric fastening applications requiring a low-profile head and secure hex socket drive. Measuring 16mm in length under the head and fully threaded, this screw is manufactured from 18-8 austenitic A2 stainless steel with a bright, uncoated finish. The button head style reduces snag points and distributes clamping load over a wider bearing surface than a standard cap head. The 2mm hex socket drive accepts a standard ball-end or straight hex key. This fastener conforms to ISO 7380 and carries a 4G/6G thread fit class with right-hand thread direction. Sold in a package of 25 pieces.

This fastener is suited for light mechanical assemblies, enclosures, panel mounting, and precision equipment where a flush or low-profile head is required and corrosion resistance is a priority. The A2 stainless steel construction makes it appropriate for indoor and mildly corrosive environments. Machinists, millwrights, equipment technicians, and field service professionals commonly use this screw in instrumentation, electronics enclosures, HVAC equipment panels, and general fabrication work where metric fasteners are specified.

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw. Compatible with any M3x0.50 threaded insert, nut, or tapped hole conforming to metric thread standards.

Installation Notes

Install using a 2mm hex key or ball-end driver; do not overtighten in soft or thin base materials, as the small thread diameter limits clamp load. Ensure mating threads are clean and free of debris before installation. A2 stainless fasteners are susceptible to galling under high torque — apply a compatible anti-seize compound when threading into stainless tapped holes. Follow applicable mechanical or equipment manufacturer specifications for torque requirements.
