Value Collection 643229PS M20 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643229PS is a metric hex head cap screw designed for general industrial fastening applications. It features an M20 x 2.50 thread profile with a 50 mm length under head and is fully threaded from tip to bearing surface. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 933 and ISO 4017 standards, making it a reliable choice for structural and mechanical assemblies where a recognized international thread specification is required. It is installed using a 30 mm hex wrench or socket.

This screw is suited for metric fastening applications in industrial machinery, structural steel fabrication, equipment assembly, and maintenance operations. The fully threaded design provides engagement along the entire shank, which is advantageous in through-bolt applications or where thread engagement depth must be maximized. Maintenance technicians, millwrights, and industrial mechanics commonly use this fastener in both light and heavy equipment contexts.

Key Features

• M20 x 2.50 metric thread size, fully threaded along entire length
• 50 mm length under head for standard through-bolt and clamped joint applications
• Grade 8.8 steel construction provides consistent mechanical strength for general industrial use
• Bright, uncoated finish suitable for dry or indoor fastening environments
• Compliant with DIN 933 and ISO 4017 international standards
• 30 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as an OEM-style metric hex head cap screw conforming to DIN 933 and ISO 4017 specifications, suitable for use wherever an M20 x 2.50 fully threaded fastener is required.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and appropriate 30 mm metric socket or open-end wrench. Verify mating thread condition and hole alignment before installation to prevent cross-threading. Do not use impact tools at final torque without a calibrated torque-limiting device. Always follow the equipment manufacturer's torque specification and fastener reuse guidelines for the specific joint being assembled.
