Value Collection 643597PS M6x1 90mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643597PS is a metric hex head cap screw used to fasten components in mechanical, structural, and industrial assemblies. It carries an M6 x 1.00 thread and measures 90 mm under the head, with full threading along the entire shank. Manufactured from Grade 8.8 steel with a bright uncoated finish, it meets DIN 933 and ISO 4017 standards. The 10 mm hex drive allows installation with standard metric hex tools. Licensed trade professionals and industrial maintenance technicians rely on this fastener for equipment assembly, panel mounting, and general mechanical joining applications.

This screw is suited for metric fastening applications across a wide range of industries including HVAC equipment assembly, electrical enclosure fabrication, plumbing system component mounting, and general mechanical maintenance. It performs in both light structural and non-structural roles wherever an M6 fully threaded metric cap screw is specified. The Grade 8.8 rating indicates medium-high tensile strength, making it appropriate for joints requiring reliable clamping force without the need for a hardened or alloy fastener.

Key Features

• M6 x 1.00 metric thread with 90 mm length under head for deep engagement
• Fully threaded shank provides maximum thread engagement across the entire bolt length
• Grade 8.8 steel construction delivers medium-high tensile and proof load ratings
• Bright uncoated finish — suitable for dry or lightly protected indoor environments
• Conforms to DIN 933 and ISO 4017 dimensional standards for consistent interchangeability
• 10 mm hex head accepts standard metric wrenches and sockets

Compatibility

Designed as a standard metric replacement or maintenance fastener for any application requiring an M6 x 1.00 fully threaded hex head cap screw per DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is typically performed by mechanical, HVAC, or electrical trade technicians using a metric wrench or socket set. De-energize all electrical systems and relieve mechanical loads before disassembling or replacing fasteners in live equipment. Verify thread pitch and length match the existing hole specification before installation to avoid cross-threading or insufficient clamp length. Always apply consistent torque using a calibrated torque wrench where joint specifications require it.
