Value Collection 643264PR Hex Head Cap Screw M12x1.25 60mm

Product Description

The VALUE COLLECTION 643264PR is a metric hex head cap screw designed for precision fastening in mechanical and structural assemblies. Sized at M12 x 1.25 with a 60 mm length under head, this fastener is fully threaded along its entire shank. It is manufactured from Grade 8.8 steel, indicating a medium-high tensile strength suitable for demanding bolted joints. The 19 mm hex drive allows for standard wrench or socket installation. Conforming to DIN 961 and ISO 8676 standards, this screw is the correct choice where metric fine-thread specifications are called out on engineering drawings or OEM documentation.

This fastener is used across industrial maintenance, equipment manufacturing, automotive, and general mechanical assembly applications where a fine-pitch M12 thread is required. The fine 1.25 mm pitch provides better vibration resistance and more precise clamping control compared to a coarse-thread equivalent. It is appropriate for use in metal-to-metal joints, machinery frames, brackets, and similar structural connections. Technicians in HVAC equipment manufacturing, plumbing fixture assembly, and industrial service work will encounter this size in OEM hardware specifications.

Key Features

• M12 x 1.25 fine metric thread for precise torque control and improved vibration resistance
• 60 mm length under head, fully threaded for maximum thread engagement
• Grade 8.8 steel construction provides medium-high tensile and proof load strength
• 19 mm hex size compatible with standard metric wrenches and sockets
• Bright uncoated finish — no additional coating that could affect dimensional tolerances
• Meets DIN 961 and ISO 8676 standards for dimensional and mechanical conformance

Compatibility

Designed as an OEM-style metric fine-thread replacement fastener for M12 x 1.25 threaded applications conforming to DIN 961 and ISO 8676 dimensional standards.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque specifications for Grade 8.8 hardware. Always verify thread engagement depth and ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench to achieve the correct clamping load as specified in the equipment service documentation — do not rely on feel alone for structural joints. Inspect threads on both the fastener and the receiving component for damage before assembly.
