Value Collection 644043PS M8 X 1.25 X 35mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644043PS is a metric hex head cap screw designed for mechanical fastening applications requiring a partially threaded shank. It is manufactured from Grade 8.8 steel with a bright, uncoated finish. The screw measures M8 x 1.25 thread pitch with a 35 mm length under the head and uses a 13 mm hex drive. Grade 8.8 denotes a medium-high strength carbon steel fastener capable of handling demanding load requirements. It conforms to DIN 931 and ISO 4014 standards for partially threaded metric hex cap screws. This fastener is installed by millwrights, maintenance technicians, and mechanical assemblers across a wide range of industrial and commercial applications.

This screw is suited for general-purpose metric bolted assemblies in industrial machinery, equipment frames, structural fixtures, and mechanical sub-assemblies where a partially threaded shank is required to allow the unthreaded grip length to bear shear loads. The DIN 931 and ISO 4014 compliance makes it interchangeable with other metric hex cap screws meeting those same standards. It is appropriate for residential, commercial, and industrial maintenance and repair operations requiring a reliable M8 fastener.

Key Features

• Grade 8.8 steel construction provides reliable tensile and yield strength for medium-high load applications
• Partially threaded shank per DIN 931 and ISO 4014 allows the grip zone to carry shear loads without thread engagement
• M8 x 1.25 thread pitch with 35 mm length under head suits a wide range of standard metric assemblies
• 13 mm hex drive is compatible with standard metric wrenches and sockets
• Bright, uncoated finish maintains dimensional precision without added coating thickness

Compatibility

Designed as a standard metric hex cap screw conforming to DIN 931 and ISO 4014, suitable for use in any M8 x 1.25 threaded application requiring a partially threaded fastener meeting those specifications.

Installation Notes

This fastener is typically installed by millwrights, mechanical assemblers, or maintenance technicians using standard metric hand tools or power tools with a 13 mm socket or open-end wrench. Always ensure mating threads are clean and free of debris before installation. Follow applicable equipment manufacturer torque specifications for M8 Grade 8.8 fasteners as dictated by the assembly drawings or service documentation. Do not exceed the rated mechanical limits of the fastener by substituting it in applications requiring higher-grade hardware.
