Value Collection HC3X03030-050BX Hex Head Cap Screw M3

Product Description

The VALUE COLLECTION HC3X03030-050BX is a fully threaded hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. The fastener features an M3 x 0.50 mm thread pitch and a 30 mm length under head. The 5.5 mm hex drive head conforms to DIN 933 standards, ensuring dimensional interchangeability with other DIN 933-compliant hardware. This screw is sold in a minimum order quantity of 50 pieces, making it appropriate for production, assembly, or MRO procurement scenarios. Installers across plumbing, HVAC, electrical panel assembly, and light fabrication applications regularly specify stainless fasteners of this type for corrosion-resistant connections.

This fastener is suited for metric-threaded assemblies in environments where corrosion resistance is required. The 18-8 austenitic Grade A2 stainless steel construction provides solid performance in wet, humid, or mildly corrosive conditions. Typical applications include equipment panels, enclosures, brackets, and mechanical assemblies where a fully threaded M3 hex cap screw is specified. The DIN 933 standard governs the head geometry and thread form, making this screw dimensionally consistent with metric hardware used across a wide range of trade and industrial equipment.

Key Features

• Fully threaded along the 30 mm shank length for maximum thread engagement in shallow or thin-material installations
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance in damp or humid environments
• DIN 933 compliant for dimensional consistency with standard metric hex head hardware
• Bright uncoated finish — no plating to flake, chip, or introduce dimensional variation
• 5.5 mm hex drive head compatible with standard metric hex wrenches and sockets
• Minimum order quantity of 50 units supports production and bulk MRO purchasing

Compatibility

Designed for use in any metric-threaded assembly requiring an M3 x 0.50 mm fully threaded hex head cap screw conforming to DIN 933 dimensional standards.

Installation Notes

Installation is performed with a standard 5.5 mm hex wrench or appropriately sized socket. Power down or de-energize any equipment before accessing fastener locations within electrical or HVAC enclosures. Do not mix metric and imperial fasteners in the same assembly, as thread forms are not interchangeable. Apply thread-locking compound or anti-seize as required by the equipment manufacturer's service documentation.
