Value Collection 644554PR M4 Hex Head Cap Screw 30mm

Product Description

The VALUE COLLECTION 644554PR is a metric hex head cap screw designed for general mechanical fastening applications. It features an M4 x 0.70 thread profile with a 30 mm length under the head and partial threading along the shank. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener meets the dimensional and mechanical requirements of DIN 931 and ISO 4014. The 7 mm hex drive allows installation with standard hex wrenches or sockets. Grade 8.8 steel provides a reliable strength-to-weight ratio for medium-duty structural and mechanical assemblies.

This screw is suited for metric fastening applications across a range of industries, including HVAC equipment assembly, electrical enclosure fabrication, plumbing fixture mounting, and general mechanical maintenance. The partially threaded shank is appropriate for clamping applications where a smooth shank bearing surface is needed between joined components. Sold individually with a minimum order quantity of 100 pieces, this fastener is intended for professional and production use where consistent dimensional tolerances are required.

Key Features

• M4 x 0.70 metric thread, partially threaded shank per DIN 931 and ISO 4014
• Grade 8.8 steel construction for medium-duty tensile strength
• Bright uncoated finish suitable for use in dry or controlled environments
• 7 mm hex drive compatible with standard metric hex wrenches and sockets
• 30 mm length under head for consistent clamping depth
• Minimum order quantity of 100 pieces supports production and service inventory

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 931 and ISO 4014, suitable for any application requiring an M4 x 0.70 partially threaded fastener in Grade 8.8 steel.

Installation Notes

Install using a metric hex wrench or socket sized to 7 mm. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated tensile load for Grade 8.8 fasteners at the M4 diameter. Follow applicable equipment manufacturer torque guidelines and relevant mechanical codes when fastening structural or pressure-bearing components.
