Value Collection C90490 M20x2.50x150mm Hex Cap Screw

Product Description

The Value Collection C90490 is a metric hex head cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. It features an M20 x 2.50 thread with a 150 mm length under head and is partially threaded, leaving a smooth shank section near the head. Manufactured from Grade 10.9 steel with a zinc-plated finish, this fastener delivers the tensile strength and corrosion resistance required in demanding service environments. A 30 mm hex drive size allows installation with standard hex wrenches or impact tooling. It conforms to DIN 931 and ISO 4014 dimensional standards.

This cap screw is suited for general industrial maintenance, heavy equipment assembly, machinery fabrication, and structural bolting where metric fasteners and high material grade are specified. The partial thread design is typical in applications requiring a grip length through clamped material before thread engagement begins, making it appropriate for through-bolt configurations and flanged connections where shank bearing load matters.

Key Features

• M20 x 2.50 metric thread with 150 mm length under head
• Grade 10.9 steel provides high tensile and proof load strength
• Zinc-plated finish for corrosion protection in general service environments
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 30 mm hex drive compatible with standard wrenches and impact sockets

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 931 and ISO 4014, suitable for use in any application specifying an M20 x 2.50 x 150 mm Grade 10.9 partially threaded fastener.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or mechanical assemblers using a 30 mm open-end, box, or impact wrench. Torque to the value specified in the applicable engineering drawing or equipment service manual for Grade 10.9 fasteners at this thread size. Ensure mating threads are clean and free of debris before installation. Do not reuse fasteners that show signs of thread damage, galling, or elongation from prior torque loading.
