Value Collection B10648 Hex Head Cap Screw M20 X 1.50

Product Description

The VALUE COLLECTION B10648 is a metric hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 10.9 steel with a bright uncoated finish, this screw delivers the tensile performance required in demanding bolted connections. The fastener measures M20 x 1.50 thread pitch with a 90 mm length under head and features partial threading per DIN 931 standards. The 30 mm hex drive size accommodates standard hex wrenches and impact sockets used by maintenance mechanics, millwrights, and assembly technicians working to metric specifications.

This screw is suited for use in metric-standard machinery, fabricated steel structures, and equipment assemblies where a partially threaded shank is required to maintain shear strength across a joint. The DIN 931 partial-thread configuration leaves an unthreaded grip length beneath the head, which is appropriate for bolted connections where the fastener passes through a clearance hole before engaging a threaded bore or nut. Sold in a package quantity of five, this screw is a practical choice for field repairs, maintenance stock, or assembly line replenishment.

Key Features

• Grade 10.9 steel construction for high-tensile bolted connections
• M20 x 1.50 thread pitch with 90 mm length under head
• Partially threaded shank per DIN 931 standard
• Bright uncoated finish for standard indoor and dry-environment use
• 30 mm hex drive compatible with standard metric sockets and wrenches
• Metric thread standard for use in metric-spec assemblies

Compatibility

Designed as an OEM-style replacement or maintenance fastener for metric-standard machinery and structural assemblies requiring a DIN 931 partially threaded hex head cap screw in M20 x 1.50 x 90 mm with Grade 10.9 steel.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener specifications and torque requirements for Grade 10.9 hardware. Always consult the equipment manufacturer's torque specification chart for M20 Grade 10.9 fasteners before final tightening. Inspect mating threads for damage or contamination before assembly and ensure the clearance hole diameter is appropriate for the M20 shank. Do not substitute Grade 10.9 fasteners with lower-grade hardware in applications where the original specification calls for high-tensile bolting.
