Value Collection 644286PR M14x1.5 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 644286PR is a metric hex head cap screw sized M14 x 1.50 with a 55 mm length under head. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener delivers reliable tensile strength for general structural and mechanical assemblies. The partially threaded shank provides a bearing surface that resists joint slippage under load. The 22 mm hex drive accommodates standard hex wrenches and sockets. Compliance with DIN 960 and ISO 8765 standards ensures dimensional consistency and interchangeability across metric fastener applications. This screw is a practical choice for maintenance, OEM assembly, and fabrication work.

This fastener suits a broad range of industrial, mechanical, and trade applications where a fine-pitch metric cap screw is required. The M14 x 1.50 fine thread pitch offers greater resistance to loosening under vibration compared to coarse-pitch alternatives, making it well suited for machinery, equipment mounting, automotive, and structural steel applications. It is commonly installed by maintenance technicians, millwrights, pipefitters, and fabricators working in commercial and industrial environments.

Key Features

• M14 x 1.50 fine metric thread for improved vibration resistance
• 55 mm length under head suits medium-depth through-bolt and tapped-hole applications
• Grade 8.8 steel construction provides high tensile strength for structural use
• Partially threaded shank creates a clean grip zone between mating parts
• 22 mm hex drive compatible with standard metric sockets and wrenches
• Meets DIN 960 and ISO 8765 dimensional standards for consistent fitment

Compatibility

Designed for use in any application requiring a DIN 960 or ISO 8765 compliant M14 x 1.50 fine-pitch hex head cap screw with partial threading and a 55 mm length under head.

Installation Notes

Installation should be performed by a qualified technician using a calibrated torque wrench and the appropriate 22 mm socket or wrench. Always verify thread engagement depth and confirm the receiving material is rated for the fastener grade before final torquing. Do not mix metric and standard fasteners in the same joint. Follow applicable equipment manufacturer specifications and industry standards for torque values relevant to Grade 8.8 fasteners in the specific application.
