Value Collection 643249PS Hex Head Cap Screw M12x1.5x25mm

Product Description

The VALUE COLLECTION 643249PS is a metric hex head cap screw designed for fastening applications that require a fully threaded shank and close thread pitch control. It is manufactured from Grade 8.8 steel with a bright, uncoated finish. The screw measures M12 x 1.50 thread size with a 25 mm length under head and a 19 mm hex drive. It conforms to DIN 961 and ISO 8676 standards, making it a recognized choice for precision metric assemblies. Machinists, millwrights, and maintenance technicians commonly specify Grade 8.8 hardware for structural and mechanical fastening work where consistent tensile strength is required.

This screw is suited for general industrial, mechanical, and maintenance applications involving metric-threaded assemblies. The fine 1.50 mm thread pitch provides better resistance to loosening under vibration compared to coarse-pitch alternatives at the same diameter. It is a fully threaded fastener, meaning the threads run the full length of the shank under the head, making it appropriate for through-bolting or use with threaded inserts where maximum thread engagement is needed. It is sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• M12 x 1.50 fine thread pitch conforming to DIN 961 and ISO 8676 standards
• Fully threaded shank for maximum thread engagement along the entire fastener length
• Grade 8.8 steel construction providing medium-high tensile strength suitable for structural fastening
• 19 mm hex drive compatible with standard metric hex sockets and wrenches
• Bright, uncoated finish — suitable for applications where additional coating is applied post-installation or not required
• Recognized UNSPSC classification 31161501 for procurement and inventory systems

Compatibility

Designed as an OEM-style and general-purpose replacement or specification fastener for metric assemblies requiring an M12 x 1.50 fine-thread hex head cap screw per DIN 961 and ISO 8676 standards.

Installation Notes

Installation should be performed by a qualified millwright, machinist, or maintenance technician familiar with metric fastener specifications. Always verify thread engagement length and mating thread condition before installation. Use a calibrated torque wrench to achieve the correct clamp load for Grade 8.8 fasteners per applicable engineering specifications — do not rely on feel alone. Ensure the mating hole or nut is also rated for the load and thread class to avoid stripping or joint failure.
