Value Collection HC3X03005-050BX M3 Hex Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION HC3X03005-050BX is a metric hex head cap screw sized M3 x 0.50 with a 5 mm length under the head. Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener delivers corrosion resistance suitable for wet, chemical-exposed, or outdoor environments. It is fully threaded along the shank and left uncoated, retaining a bright finish. The 5.5 mm hex drive allows installation with standard metric hex wrenches or sockets. Compliance with DIN 933, EN 24017, and ISO 4017 confirms dimensional consistency for applications requiring interchangeable metric hardware. Maintenance technicians, pipefitters, and equipment assemblers working with metric-dimensioned assemblies will find this screw a straightforward OEM-style replacement or general-use fastener.

This screw is suited for light-duty mechanical assemblies, equipment enclosures, instrumentation panels, HVAC component brackets, and plumbing fixture mounts where metric thread sizing is required. The M3 x 0.50 thread pitch is common in smaller mechanical subassemblies and panel-mounted components. The A2 stainless grade makes it appropriate for indoor and moderately corrosive outdoor installations where carbon steel fasteners would be prone to rust staining or degradation over time.

Key Features

• Bright uncoated finish — no coating thickness to account for in tight tolerance fits
• 5.5 mm hex drive compatible with standard metric wrenches and sockets
• Meets DIN 933, EN 24017, and ISO 4017 dimensional standards

Compatibility

Designed as an OEM-style replacement or general-use metric fastener for assemblies specifying M3 x 0.50 hex head cap screws per DIN 933, EN 24017, or ISO 4017.

Installation Notes

Installation is performed by maintenance technicians and assemblers using a 5.5 mm open-end wrench, box wrench, or metric socket. Always power down or de-energize any equipment before accessing fastened components in electrical or HVAC assemblies. Do not mix stainless steel fasteners with dissimilar metals in highly conductive or galvanic-sensitive environments without appropriate isolation. Follow equipment manufacturer torque guidelines — no specific torque value is published for this fastener in the available product data.
