Value Collection 643520PS M3 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643520PS is a metric hex head cap screw designed for general fastening applications across mechanical, structural, and equipment assembly work. Sized M3 x 0.50 with a 12 mm length under head, this screw is fully threaded and manufactured from Grade 8.8 steel, which provides a tensile strength suitable for medium-duty bolted joints. The bright, uncoated finish leaves the steel surface bare, making it appropriate for indoor or controlled environments where corrosion exposure is minimal. A 5.5 mm hex head drive allows installation with standard metric wrenches or sockets. Machinists, maintenance technicians, and mechanical assemblers regularly stock this fastener for production and repair work.

This screw suits residential and commercial equipment assembly, machine maintenance, panel mounting, and light structural fastening where a metric thread pattern is required. Conformance to DIN 933 and ISO 4017 standards ensures dimensional consistency for use in internationally specified assemblies. The fully threaded shank provides maximum thread engagement in thinner materials and tapped blind holes, making it a common choice in OEM equipment builds and field service repairs.

Key Features

• M3 x 0.50 metric thread — fully threaded shank for maximum engagement in thin stock and tapped holes
• Grade 8.8 steel construction — medium-high tensile strength for reliable bolted joints
• 12 mm length under head — compact size suited for tight-clearance assemblies
• 5.5 mm hex head drive — compatible with standard metric wrenches and sockets
• Bright uncoated finish — dimensionally consistent surface for precise fit in DIN 933 and ISO 4017 specified applications
• Conforms to DIN 933 and ISO 4017 dimensional standards

Compatibility

Designed as a standard metric replacement or stock fastener for any application specifying an M3 x 0.50 x 12 mm fully threaded hex head cap screw per DIN 933 or ISO 4017.

Installation Notes

Installation is performed by mechanics, machinists, or maintenance technicians using a metric wrench or socket sized to the 5.5 mm hex head. Always verify that the mating tapped hole or nut matches the M3 x 0.50 thread pitch before installation. Do not exceed the torque rating appropriate for Grade 8.8 fasteners at this diameter, and refer to applicable engineering specifications for your assembly. Ensure fastener and mating surface are clean and free of debris before seating.
