Value Collection BHS7X03030-050BX M3x0.5 Button Cap Screw

Product Description

The VALUE COLLECTION BHS7X03030-050BX is a partially threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and a clean, corrosion-resistant finish. Manufactured from A2 grade 18-8 stainless steel with a bright uncoated surface, this screw meets ANSI/ASME B18.3.4M and ISO 7380 standards. The M3x0.5 thread size and 30 mm length under head make it suited for light structural and mechanical assembly work. Drive engagement is via a 2 mm hex socket, requiring an appropriate Allen key or hex bit driver. This fastener is typically installed by millwrights, maintenance technicians, and mechanical assemblers across industrial and commercial maintenance settings.

This screw is intended for use in metric-threaded assemblies where a low-profile button head is required to sit flush or near-flush against a mating surface. The right-hand 6G thread fit class ensures consistent engagement with standard metric tapped holes. Its stainless steel construction makes it suitable for environments with moderate moisture or corrosion exposure. The minimum order quantity of 50 pieces makes this SKU appropriate for service stock, maintenance kits, or production-level assembly work.

Key Features

• A2 grade 18-8 stainless steel construction for corrosion resistance
• Button head profile provides low clearance in confined assemblies
• 2 mm hex socket drive for precise torque application
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards
• Right-hand 6G thread fit class for reliable metric thread engagement
• Partially threaded shank on 30 mm length under head

Compatibility

Designed for use in standard metric M3x0.5 tapped holes conforming to ISO and ANSI thread specifications. Suitable as a direct replacement or service stock fastener in any assembly calling for an ISO 7380 button socket cap screw in M3x0.5 with a 30 mm grip length.

Installation Notes

Installation requires a 2 mm hex key or hex socket bit driver. Verify that the receiving tapped hole conforms to M3x0.5 metric thread standards before installation. Avoid over-torquing stainless steel fasteners, as galling can occur without appropriate anti-seize compound. Power down or de-energize any equipment before performing fastener service on electrical enclosures or mechanical assemblies.
