The VALUE COLLECTION 643525PS is a metric hex head cap screw designed for general mechanical assembly and structural fastening applications. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fully threaded fastener measures M3 x 0.50 thread pitch with a 20 mm length under head and a 5.5 mm hex drive. Grade 8.8 designation indicates a medium-high tensile strength carbon steel construction, suitable for load-bearing connections where consistent clamp force is required. This screw conforms to DIN 933 and ISO 4017 standards, ensuring dimensional accuracy and interchangeability with other metric-compliant hardware. Weighing approximately 0.01 pounds per unit, it is well suited for compact assemblies and precision equipment.
This fastener is appropriate for use in light industrial, mechanical, and trade service environments where metric fasteners are specified. Common applications include HVAC equipment panels, electrical enclosure assembly, pump and motor mounting, and general equipment fabrication. The fully threaded shank allows engagement along the entire fastener length, making it effective in thin-material or close-tolerance applications. Installation is performed by qualified mechanical technicians or tradespeople using a standard 5.5 mm hex wrench or socket.
Designed as an OEM-style metric hex head cap screw conforming to DIN 933 and ISO 4017 standards, compatible with any M3 x 0.50 threaded application requiring a fully threaded fastener.
Power down or de-energize any equipment before disassembling panels or enclosures to access fastener locations. Use a calibrated torque wrench rated for M3 hardware and follow the equipment manufacturer torque specifications for Grade 8.8 metric fasteners. Inspect threads for contamination or damage before installation. Uncoated fasteners are not recommended for outdoor or high-humidity environments without additional corrosion protection.
