Value Collection 643241PS Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 643241PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It features an M20 x 2.50 thread profile with a 90 mm length under head, manufactured from Grade 8.8 steel in a bright, uncoated finish. The screw is fully threaded along its entire shank and conforms to DIN 933 and ISO 4017 standards, ensuring dimensional consistency for use in precision assemblies. Weighing 0.573 pounds per unit, this fastener suits medium-to-heavy-duty bolted connections where a standardized metric hex drive is required. Technicians and tradespeople working with metric-spec equipment will find this screw a direct fit for a wide range of structural and mechanical joint applications.

This fastener is suited for use in industrial machinery, structural steel assemblies, HVAC equipment mounting, and mechanical systems that call for metric M20 fasteners. The fully threaded design maximizes thread engagement across the full fastened length, making it appropriate for through-bolt applications and joints where nuts are used on both sides of a connection. The Grade 8.8 steel construction provides a reliable strength level for demanding service conditions without the added cost of higher-alloy grades.

Key Features

• M20 x 2.50 metric thread profile, 90 mm length under head
• Fully threaded shank per DIN 933 and ISO 4017 standards
• Grade 8.8 steel construction for reliable medium-to-heavy-duty load bearing
• Bright, uncoated finish suitable for indoor and controlled-environment use
• 30 mm hex drive size for standard metric wrench and socket compatibility

Compatibility

Designed as a standard metric hex head cap screw for any application requiring an M20 x 2.50 x 90 mm fastener conforming to DIN 933 or ISO 4017 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a calibrated torque wrench sized for a 30 mm hex fastener. De-energize or lock out any equipment before fastener removal or replacement in live assemblies. Apply thread lubrication only if called for by the joint specification, as dry-torque values differ from lubricated values. Always verify that mating threads and bearing surfaces are clean and free of damage before assembly.
