Value Collection 644141PR M12x1.75x75mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644141PR is a metric hex head cap screw engineered for general-purpose mechanical and structural fastening applications. Built to Grade 8.8 steel, it delivers a strong balance of tensile strength and ductility suited to bolted assemblies where controlled clamping force is required. The screw features a partially threaded shank with an M12 x 1.75 thread profile and a length under the head of 75 mm, with a 19 mm hex drive. The bright, uncoated finish leaves the base steel exposed, making it appropriate for dry or protected indoor environments. Machinists, millwrights, pipefitters, and maintenance technicians commonly install this fastener in machinery, structural frames, and equipment assemblies.

This cap screw is suited to metric-threaded assemblies in both light industrial and commercial maintenance contexts. The partially threaded design provides an unthreaded grip length along the shank, which is critical in applications where shear load distribution matters or where the fastener passes through clearance holes before engaging a tapped bore. It conforms to DIN 931 and ISO 4014 dimensional standards, making it interchangeable with other hardware meeting those specifications. Sold individually with a minimum order quantity of 50 pieces.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in bolted joints
• M12 x 1.75 metric thread with 75 mm length under head for deep-reach fastening
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 19 mm hex drive compatible with standard metric wrenches and sockets
• Bright, uncoated finish for use in controlled or protected environments

Compatibility

Designed as a standard metric replacement or stock fastener for any M12 x 1.75 tapped hole or nut requiring a partially threaded hex cap screw per DIN 931 or ISO 4014.

Installation Notes

Installation is performed by qualified millwrights, machinists, or maintenance technicians using a metric wrench or socket sized to 19 mm. Ensure mating threads are clean and free of debris before installation. Do not mix metric and unified thread fasteners in the same assembly. Follow applicable equipment manufacturer torque specifications and relevant standards such as ASME or ISO bolting guidelines for the joint classification.
