Value Collection KP82426 M3x0.50 Button Cap Screw 25pk

Product Description

The VALUE COLLECTION KP82426 is a fully threaded button socket cap screw in M3x0.50 thread size with an 8mm length under the head. Manufactured from 18-8 (A2) stainless steel with a bright, uncoated finish, this fastener meets ISO 7380 standards and is suited for metric assembly applications requiring a low-profile head. The hex socket drive accepts a 2mm hex key for installation. This screw ships in a package of 25 pieces, making it a practical bench-stock item for machine shops, maintenance crews, and assembly technicians working with metric hardware.

This fastener is used in precision mechanical assemblies, equipment enclosures, and machine components where a flush or low-profile head is needed and corrosion resistance is a priority. The right-hand thread and 4G/6G thread fit class ensure consistent engagement with standard metric tapped holes. Suitable for light-duty structural and non-structural fastening in both indoor and mildly corrosive environments. Typically installed by machinists, maintenance technicians, and assembly professionals across industrial and commercial applications.

Key Features

Compatibility

Designed as a metric replacement or stock fastener for any application requiring an ISO 7380 button socket cap screw in M3x0.50 thread size with an 8mm length under the head.

Installation Notes

Install with a 2mm hex key or matching hex socket bit; do not use an undersized driver as it will strip the socket. Ensure the receiving hole is properly tapped to M3x0.50 metric thread before installation. When installing stainless steel fasteners into stainless steel components, apply an anti-seize compound to prevent galling during tightening. Follow applicable mechanical assembly standards for torque guidance based on joint requirements.
