Value Collection C90486 Hex Head Cap Screw M20x2.50x110mm

Product Description

The VALUE COLLECTION C90486 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 zinc-plated finish, this fastener delivers substantial clamping force and corrosion resistance suitable for demanding service environments. The screw features an M20 x 2.50 thread profile, a 110 mm length under head, and is partially threaded per DIN 931 and ISO 4014 standards. The 30 mm hex drive size is compatible with standard metric wrenches and impact tools. This fastener is appropriate for use by millwrights, maintenance technicians, and mechanical assemblers working on heavy equipment, machinery, and structural connections.

This cap screw is suited for metric-standard assemblies requiring high clamping loads where a partially threaded shank provides a bearing surface between mating components. Typical applications include equipment mounting, machinery frames, structural steel connections, and industrial fabrication. The DIN 931 and ISO 4014 compliance ensures dimensional consistency with other metric hardware in the assembly. It is well-suited for both original equipment manufacturing and field repair or replacement work in production and maintenance settings.

Key Features

• Grade 10.9 steel construction provides high tensile and proof load capacity
• Zinc-plated finish offers baseline corrosion protection in moderate environments
• Partially threaded shank per DIN 931 and ISO 4014 standards ensures dimensional consistency
• M20 x 2.50 metric thread profile with 110 mm length under head
• 30 mm hex drive accommodates standard metric 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 metric-standard fastener application requiring an M20 x 2.50 partially threaded cap screw.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with metric fastener torque requirements for Grade 10.9 hardware. Use a calibrated torque wrench sized for the 30 mm hex to achieve proper clamp load per the applicable engineering specification for the assembly. Ensure mating threads are clean, undamaged, and free of debris before installation. Do not use this fastener as a substitute for Grade 8.8 or lower-rated hardware where a higher strength class is specified by the equipment manufacturer.
