Value Collection 643227PS M20 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643227PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener provides reliable tensile strength suited to moderate-to-high load assemblies. The M20 x 2.50 thread profile runs fully along the 45 mm length under the head, eliminating the partial-thread grip zone and ensuring thread engagement from tip to shoulder. The 30 mm hex drive accepts standard metric wrenching. Conformance to DIN 933 and ISO 4017 ensures dimensional interchangeability with other fasteners meeting those standards.

This cap screw is commonly used in industrial machinery, structural steel assemblies, equipment frames, and fabrication work where a metric fastener with full threading is required. The uncoated finish is appropriate for dry or controlled environments or where a coating will be applied after assembly. Maintenance technicians, millwrights, and fabricators will encounter this fastener in a wide range of plant and field applications requiring M20 metric hardware.

Key Features

• M20 x 2.50 metric thread, fully threaded over the 45 mm length under head
• Grade 8.8 steel construction for dependable tensile and yield strength in structural fastening
• 30 mm hex drive compatible with standard metric open-end, box, and socket wrenches
• Bright uncoated finish suitable for post-assembly coating or controlled-environment use
• Conforms to DIN 933 and ISO 4017 dimensional standards for drop-in interchangeability

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017, making it dimensionally interchangeable with any M20 x 2.50 x 45 mm fastener meeting those standards.

Installation Notes

Installation is performed with a 30 mm metric wrench or socket. Always clean and inspect threaded holes before installation to remove debris that could cause false torque readings or thread damage. Follow the equipment manufacturer's torque specifications for M20 Grade 8.8 fasteners, as no torque value is specified for this part in isolation. Discard any fastener showing thread deformation, corrosion, or other visible damage before use.
