Value Collection BHS7X03020-050BX M3x0.5 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION BHS7X03020-050BX is a partially threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and clean appearance. Built from A2 (18-8) stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance for general-purpose industrial and mechanical assemblies. The M3x0.5 thread size and 20 mm length under head make it suited to light-duty clamping and panel attachment tasks. Drive engagement is via a 2 mm hex socket. Compliant with ANSI/ASME B18.3.4M and ISO 7380 standards. Sold in a minimum order quantity of 50 pieces per box.

This fastener is used across a wide range of light mechanical, electronic enclosure, HVAC panel, plumbing fixture bracket, and general fabrication applications where a button-head profile is needed to reduce snag points or clear adjacent components. The ISO 7380 button-head geometry distributes clamping load over a wider bearing surface compared to a standard socket head, making it a common choice for sheet metal, plastic housings, and thin-section assemblies. Trade mechanics, fabricators, and maintenance technicians regularly stock this size for service and assembly work.

Key Features

• A2 (18-8) stainless steel construction for corrosion resistance in general-purpose environments
• Button head profile per ISO 7380 for low-profile, snag-reducing installation
• M3x0.5 metric thread with 6G thread fit class for consistent engagement tolerance
• 2 mm hex socket drive for precise torque application with standard hex keys
• Bright uncoated finish maintains dimensional accuracy and galvanic compatibility with stainless assemblies
• Right-hand thread direction, partially threaded shank

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw in M3x0.5, compatible with any threaded hole or nut conforming to M3x0.5 6H metric thread specifications.

Installation Notes

Install with a 2 mm hex key or hex socket bit; ensure the mating thread is clean and free of debris before engagement. Do not exceed the rated torque range for A2 stainless M3 fasteners, as overtightening can cause galling in stainless-to-stainless applications — the use of an appropriate anti-galling lubricant is generally recommended in those cases. Power down any electrical enclosure or equipment before servicing panels secured with these screws. Follow applicable ANSI or ISO assembly standards for the equipment being serviced.
