Value Collection 643559PS Hex Head Cap Screw M5 X 0.80

Product Description

The VALUE COLLECTION 643559PS is a metric hex head cap screw intended for general-purpose fastening applications in mechanical assemblies, equipment fabrication, and maintenance work. Built to Grade 8.8 steel, it delivers a tensile strength suitable for medium-duty clamping and structural fastening tasks. The screw is fully threaded with an M5 x 0.80 mm thread pitch and measures 14 mm under the head, making it a compact fastener commonly used in tight-clearance assemblies. The uncoated bright finish indicates no additional corrosion protection has been applied. Drives with an 8 mm hex key or corresponding socket. Conforms to DIN 933 and ISO 4017 standards.

This screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, light structural fabrication, and general equipment repair. The M5 thread size and 14 mm length make it a common choice for attaching brackets, flanges, guards, and covers where compact fastener geometry is required. Suitable for use in residential and commercial service settings by licensed technicians and experienced tradespeople.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength for demanding fastening applications
• Fully threaded shaft along the entire 14 mm length under head for maximum thread engagement
• M5 x 0.80 mm metric thread pitch conforms to DIN 933 and ISO 4017 standards
• 8 mm hex drive compatible with standard hex keys and sockets
• Bright uncoated finish — no added coating weight or dimensional variance from plating

Compatibility

Designed as a standard metric fastener conforming to DIN 933 and ISO 4017, suitable as a direct replacement or general-purpose hex head cap screw in any application specifying an M5 x 0.80 x 14 mm fully threaded fastener in Grade 8.8 steel.

Installation Notes

Install using an 8 mm hex socket or hex key driver. Grade 8.8 fasteners should be tightened to the torque specification listed in the equipment service manual or applicable industry standard — do not substitute a generic torque value. Bright uncoated steel is not recommended for outdoor or high-moisture environments without additional corrosion protection. Follow applicable mechanical and safety codes for the specific trade discipline in which the fastener is being used.
