Value Collection 42066 Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 42066 is a metric hex head cap screw designed for general-purpose fastening in industrial, mechanical, and structural applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, it delivers a reliable combination of tensile strength and corrosion resistance. The screw follows a partially threaded shank configuration per DIN 931 and ISO 4014 standards, with an M8 x 1.25 thread and a 65 mm length under the head. The 13 mm hex drive accepts standard hex wrenches and sockets. Licensed trades and MRO professionals use this fastener in equipment assembly, machinery mounting, and fabrication work.

This fastener is suited for metric-standard assemblies in manufacturing, maintenance, and repair operations. The partially threaded shank is appropriate for applications where a bearing surface against the material is required, such as bolted flange connections, bracket mounting, and general machine assembly. The zinc-plated finish provides a basic level of corrosion protection for indoor and light-duty outdoor use. It ships in a package quantity of 50 units, making it practical for shop stock and field service kits.

Key Features

• Grade 8.8 steel construction provides a proof load of approximately 580 MPa class tensile performance per metric fastener standards
• Partially threaded shank per DIN 931 and ISO 4014 for proper load transfer in clearance-hole applications
• Zinc-plated finish for basic corrosion resistance in dry or light-moisture environments
• 13 mm hex drive compatible with standard metric sockets and combination wrenches
• M8 x 1.25 thread pitch is the standard coarse thread for M8 diameter fasteners
• Package quantity of 50 supports shop inventory and bulk service use

Compatibility

Designed for use in metric-standard assemblies requiring an M8 x 1.25 partially threaded hex cap screw per DIN 931 or ISO 4014 specifications.

Installation Notes

Installation is performed with a standard 13 mm hex socket or combination wrench. Always confirm the mating nut or tapped hole is also M8 x 1.25 metric coarse thread before installation. De-energize or lock out any equipment before fastener replacement or removal in live machinery. Follow applicable industry torque guidelines for Grade 8.8 M8 fasteners and use a calibrated torque wrench where joint integrity is critical.
