Value Collection 644289PR Hex Head Cap Screw M14 X 1.50

Product Description

The VALUE COLLECTION 644289PR is a metric hex head cap screw engineered for bolted assemblies requiring close-tolerance thread engagement. It is manufactured from Grade 8.8 steel with a bright, uncoated finish and features a partially threaded shank. The thread specification is M14 x 1.50 with a 70 mm length under head, and the hex drive measures 22 mm across the flats. This fastener conforms to DIN 960 and ISO 8765 standards, making it a direct fit for metric mechanical assemblies. It is installed by machinists, maintenance technicians, and industrial mechanics across a wide range of structural and mechanical applications.

This cap screw is suited for use in metal-to-metal bolted joints where a partially threaded shank is required to bear shear loads or maintain precise clamping force. Typical applications include machine frames, equipment mounting, and structural steel assemblies. The metric fine-pitch thread (1.50 mm pitch on M14) provides stronger thread engagement and improved resistance to loosening under vibration compared to a coarse-pitch equivalent. This makes it particularly appropriate for equipment subject to dynamic or cyclic loading.

Key Features

• M14 x 1.50 fine-pitch metric thread for secure engagement in vibration-prone assemblies
• Grade 8.8 steel construction provides a minimum tensile strength suitable for structural bolting
• Partially threaded shank accommodates shear loading and close-tolerance clearance holes
• 22 mm hex size for standard metric wrench and socket tooling
• Bright, uncoated finish — compatible with post-installation coating or plating if required
• Conforms to DIN 960 and ISO 8765 dimensional and mechanical standards

Compatibility

Designed for use in metric bolted assemblies requiring a fine-pitch M14 x 1.50 partially threaded hex cap screw conforming to DIN 960 and ISO 8765 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a metric 22 mm wrench or socket. Apply torque in accordance with the Grade 8.8 torque specifications defined by the equipment manufacturer or applicable engineering standard — do not estimate torque values from general tables without confirming thread and joint material. Inspect the mating threaded hole for proper thread form and class of fit before assembly. Do not reuse fasteners that show signs of thread deformation, corrosion, or stretch.
