Value Collection 643546PR Hex Head Cap Screw M4x0.70x25mm

Product Description

The VALUE COLLECTION 643546PR is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, fabrication, and maintenance applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener meets DIN 933 and ISO 4017 standards. It features an M4 x 0.70 mm thread pitch, a 25 mm length under head, and a 7 mm hex drive. The Grade 8.8 designation indicates a medium-high strength carbon steel construction suitable for a broad range of structural and mechanical connections. This fastener is sold individually with a minimum order quantity of 100 pieces.

This screw is suited for light-to-medium duty fastening tasks across industrial, HVAC, electrical panel, and equipment assembly applications. Its metric thread profile makes it a standard choice for equipment manufactured to international specifications. Typical installation environments include sheet metal assemblies, motor mounts, brackets, and equipment enclosures where a compact M4 hex fastener is required. The fully threaded shank provides maximum thread engagement across the entire length under head, making it well suited for through-bolt and short-grip applications.

Installation Notes

Installation is performed with a standard 7 mm open-end wrench, box wrench, or socket driver. Verify thread engagement and mating thread condition before installation to avoid cross-threading. Apply thread locking compound if vibration resistance is required by the application. Follow applicable equipment manufacturer torque guidelines for M4 fasteners, as no specific torque value is provided with this part.
