The VALUE COLLECTION C90421 is a metric hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 10.9 steel with a zinc-plated finish, this screw delivers strong clamping force with basic corrosion resistance. The M12 x 1.75 thread size and 50 mm length under head make it a common choice for medium-to-heavy bolted connections. The partially threaded shank conforms to DIN 931, the standard for metric hex bolts with reduced thread length. Machinists, maintenance technicians, and fabricators install this fastener across a wide range of equipment and structural applications.
This cap screw is suited for general-purpose metric fastening in manufacturing, equipment assembly, automotive, and industrial maintenance environments. The Grade 10.9 rating indicates a minimum tensile strength of 1040 MPa, making it appropriate for load-bearing joints where high clamping force is required. The zinc-plated finish provides a degree of protection against light moisture and handling corrosion. It is sold in a package quantity of 10, with a minimum order quantity of 1 package. The 19 mm hex drive is compatible with standard metric wrenches and sockets.
Designed as a DIN 931 metric hex cap screw for use in any application calling for an M12 x 1.75 partially threaded bolt in Grade 10.9 steel.
Installation is performed by maintenance technicians, machinists, or fabricators using a 19 mm wrench or socket. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 10.9 M12 fasteners — do not estimate torque without consulting the relevant specification.
