Value Collection 643538PS M4 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643538PS is a metric hex head cap screw designed for general mechanical fastening applications. It features an M4 x 0.70 thread form with a 10 mm length under head and is fully threaded along its entire shank. Manufactured from Grade 8.8 steel with a bright, uncoated finish, it delivers reliable tensile strength for medium-duty clamping and assembly work. A 7 mm hex head drive allows installation with standard wrenches or hex-socket tooling. This screw conforms to DIN 933 and ISO 4017 dimensional standards, making it a straightforward, drop-in fastener for metric assemblies.

This screw is suited for use in light to medium mechanical assemblies where a fully threaded metric fastener is required. Common applications include equipment fabrication, machine component assembly, HVAC equipment panels, electrical enclosure mounting, and general trade maintenance tasks. The M4 thread size and 10 mm length make it appropriate for thin to medium material stacks where full thread engagement along the entire shank is an advantage. Installers working in metric-standard environments will find this fastener compatible with standard metric tapped holes and nuts.

Key Features

• Fully threaded shank provides maximum thread engagement for M4 applications
• Grade 8.8 steel construction meets medium-duty tensile and proof-load requirements
• Bright uncoated finish suits indoor and dry-environment assemblies
• Conforms to DIN 933 and ISO 4017 standards for consistent dimensional accuracy
• 7 mm hex head is compatible with standard metric wrenches and socket sets

Compatibility

Designed as a standard metric replacement or stock fastener for any application requiring an M4 x 0.70 x 10 mm fully threaded hex head cap screw per DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is appropriate for any qualified tradesperson or assembly technician working with metric fastener systems. Use a calibrated torque wrench or driver to avoid overtightening Grade 8.8 fasteners, which can strip tapped holes or induce thread fatigue. Ensure mating threads are clean and free of debris before installation. Follow applicable equipment manufacturer guidelines and relevant mechanical assembly codes for fastener selection and torque requirements.
