Value Collection 643253PS Hex Head Cap Screw M12x1.25x35

Product Description

The VALUE COLLECTION 643253PS is a metric hex head cap screw designed for fastening applications that require a fine-pitch thread and reliable clamping strength. Sized at M12 x 1.25 with a 35 mm length under head, the fastener is fully threaded and machined to Grade 8.8 steel, indicating a tensile strength class suited for structural and mechanical assemblies. The uncoated bright finish means no additional coating interferes with torque values or thread fit. A 19 mm hex drive size is standard for this screw, allowing use with common wrenches and sockets. This fastener conforms to DIN 961 and ISO 8676 standards, making it appropriate for precision metric assemblies in industrial, automotive, and mechanical maintenance environments.

This cap screw is used in mechanical assemblies where a fine-pitch M12 thread is specified. Fine-pitch threads provide greater resistance to loosening under vibration compared to coarse-pitch equivalents, making this screw a common choice in automotive driveline components, machine tools, hydraulic equipment mounts, and precision fabrication. Technicians and machinists working to metric standards will find this fastener appropriate for both OEM assembly and field repair work where DIN or ISO compliance is required. It is sold individually but requires a minimum order of 10 pieces per transaction.

Key Features

• M12 x 1.25 fine-pitch thread for improved vibration resistance
• 35 mm length under head, fully threaded along the shank
• Grade 8.8 steel construction for reliable mechanical strength
• Bright uncoated finish with no surface treatment to alter thread tolerances
• 19 mm hex drive compatible with standard metric wrenches and sockets
• Conforms to DIN 961 and ISO 8676 dimensional standards

Compatibility

Designed as a standard metric replacement fastener conforming to DIN 961 and ISO 8676, suitable for any application specifying an M12 x 1.25 fully threaded hex head cap screw in Grade 8.8 steel.

Installation Notes

Installation should be performed by a qualified mechanic or machinist familiar with metric fastener standards. Always verify thread engagement depth and hole condition before installation. Apply torque in accordance with the equipment manufacturer specifications for Grade 8.8 M12 fasteners. Do not mix metric fine-pitch and coarse-pitch fasteners in the same assembly.
