Value Collection 644082PR Hex Head Cap Screw M10x1.5 50mm Grade 8.8

Product Description

The VALUE COLLECTION 644082PR is a metric hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, it delivers reliable tensile strength suitable for structural and machine assembly work. The fastener measures M10 x 1.50 thread size with a 50 mm length under the head and a 17 mm hex drive. The partial threading design seats the unthreaded shank against mating surfaces, providing better shear load resistance than fully threaded fasteners in many joint configurations. Licensed trades, maintenance technicians, and fabricators install this type of fastener across a wide range of industrial and mechanical applications.

This screw is used in metric-threaded assemblies across manufacturing, equipment maintenance, structural fabrication, and mechanical installations. The partially threaded shank makes it well suited for bolted joints where the fastener passes through a clearance hole before engaging a tapped bore or nut. It conforms to DIN 931 and ISO 4014 standards, making it interchangeable with other fasteners built to those specifications. The M10 x 1.50 thread pitch is the standard coarse metric pitch for 10 mm diameter fasteners, commonly encountered in machinery and equipment of European and metric-standard design.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength for general structural fastening
• Partially threaded shank improves shear resistance and clamp load in through-bolt applications
• 17 mm hex drive accepts standard metric wrenches and sockets
• Bright uncoated finish suitable for indoor or protected installations where additional corrosion resistance is not required
• Conforms to DIN 931 and ISO 4014 dimensional and material standards

Compatibility

Designed for use in metric-threaded assemblies requiring an M10 x 1.50 coarse-pitch partially threaded hex cap screw conforming to DIN 931 or ISO 4014 standards.

Installation Notes

Installation is performed with a standard 17 mm open-end wrench, combination wrench, or socket. Verify that the mating thread is M10 x 1.50 before installation. De-energize or lock out any equipment before fastener service in accordance with applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of the fastener grade; consult published Grade 8.8 torque tables for the specific joint material and lubrication condition being used.
