Value Collection 643591PS M6 Hex Cap Screw Grade 8.8 Steel

Product Description

The VALUE COLLECTION 643591PS is a metric hex head cap screw intended for general mechanical assembly and fastening applications across industrial, HVAC, plumbing, and electrical enclosure work. It is fully threaded with an M6 x 1.00 thread profile, a 28 mm length under head, and a 10 mm hex drive. Manufactured from Grade 8.8 steel in a bright, uncoated finish, this fastener meets both DIN 933 and ISO 4017 standards, making it a widely recognized specification for structural and mechanical connections requiring verified tensile and yield strength ratings.

This screw is suited for residential and commercial equipment assembly, panel mounting, HVAC bracket and component fastening, and general maintenance work where a metric fully threaded fastener is specified. The fully threaded shank allows engagement along the entire length under head, which is especially useful in thin-material or shallow-hole applications. Technicians working on metric-spec equipment in HVAC, refrigeration, electrical, or plumbing systems will find this screw compatible with standard M6 tapped holes across a wide range of equipment.

Key Features

• M6 x 1.00 thread size with 28 mm length under head for precise metric fitment
• Fully threaded shank for maximum thread engagement in shallow or thin-material applications
• Grade 8.8 steel construction provides high tensile strength suitable for structural mechanical connections
• Bright uncoated finish allows for easy visual inspection and is ready for field use as-is
• Meets DIN 933 and ISO 4017 standards for dimensional and mechanical compliance
• 10 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard metric replacement or service fastener for any M6 x 1.00 tapped hole application conforming to DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is performed by mechanical technicians, HVAC service professionals, electricians, or plumbers as part of equipment assembly or component replacement. Power down or isolate all systems before fastener work on live equipment. Use a calibrated torque wrench when the application requires specific clamp load. Do not mix metric and unified thread fasteners in the same tapped hole.
