Value Collection 643556PS M5 X 0.80 X 6 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643556PS is a metric hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener measures M5 x 0.80 in thread size with a 6 mm length under head. The 8 mm hex drive allows installation with standard metric wrenches or sockets. Grade 8.8 designation indicates medium-high tensile strength suitable for structural and mechanical assemblies where controlled clamping force is required. Conformance to DIN 933 and ISO 4017 standards ensures dimensional consistency and interchangeability across metric fastener applications.

This screw is used in a wide range of light to medium-duty mechanical assemblies including HVAC equipment panels, electrical enclosures, pump housings, and general sheet metal fabrication. The fully threaded body maximizes thread engagement in shallow or through-hole tapped applications. It is well suited for situations where a flush or low-profile hex head is needed with full thread engagement from head to tip. Installers working with metric-dimensioned components will find this fastener compatible with standard M5 x 0.80 tapped holes.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in mechanical assemblies
• Fully threaded body maximizes thread engagement in tapped through-holes
• 8 mm hex head drive compatible with standard metric wrenches and sockets
• Bright uncoated finish suitable for interior or dry-environment fastening
• Conforms to DIN 933 and ISO 4017 dimensional standards for metric interchangeability
• M5 x 0.80 thread pitch meets standard metric coarse-thread specifications

Compatibility

Designed as a standard metric replacement fastener for any application using M5 x 0.80 fully threaded hex head cap screws per DIN 933 or ISO 4017 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque requirements for Grade 8.8 hardware. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not use an impact driver without a torque-limiting adapter, as over-torquing a small-diameter screw can strip threads or cause fastener failure. Always de-energize or shut down any equipment before accessing fastener points on live assemblies.
