Value Collection 643519PS M3 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643519PS is a metric hex head cap screw designed for general mechanical fastening in assemblies where dimensional accuracy and material strength are required. Manufactured to Grade 8.8 steel, this fastener delivers a reliable tensile and yield strength profile suited for medium- to high-stress applications. The screw carries an M3 x 0.50 thread with a 10 mm length under the head and is fully threaded from tip to head bearing surface. The uncoated bright finish makes it suitable for environments where secondary finishing or coating will be applied by the installer. Licensed trades and industrial maintenance technicians working with precision mechanical assemblies commonly specify this type of fastener.

This hex head cap screw is used in light mechanical, electrical enclosure, HVAC equipment, and general industrial assembly applications where a metric M3 thread is specified. It conforms to DIN 933 and ISO 4017 standards, making it interchangeable with other fasteners built to the same international dimensional and material specifications. The 5.5 mm hex drive accepts standard metric hex wrenches and box-end tooling. It is appropriate for both production assembly environments and field-service repair work on metric-threaded components.

Key Features

• Grade 8.8 steel construction for medium- to high-strength fastening requirements
• Fully threaded along the entire shank for maximum thread engagement in thin material applications
• M3 x 0.50 mm thread pitch conforms to standard metric specifications
• 5.5 mm hex head accepts standard metric wrenches and sockets
• Bright uncoated finish compatible with post-installation coating or plating processes
• Manufactured to DIN 933 and ISO 4017 dimensional and tolerance standards

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017, suitable for any application specifying an M3 x 0.50 x 10 mm fully threaded fastener in Grade 8.8 steel.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with metric fastener torque requirements for Grade 8.8 hardware. Always ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not substitute an Imperial fastener in a metric-threaded bore. Use a correctly sized 5.5 mm wrench or socket to prevent rounding the hex head during installation or removal.
