Value Collection C754278 Hex Head Cap Screw M8 X 1.25 55mm 10pk

Product Description

The VALUE COLLECTION C754278 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 screw delivers reliable clamping force and corrosion resistance in demanding environments. It features an M8 x 1.25 mm thread with a 55 mm length under the head and is partially threaded, making it well-suited for through-bolt and clamped-joint applications. The 13 mm hex drive allows use with standard metric sockets and wrenches. This SKU is sold in a pack of 10.

This screw is intended for use in metric fastening applications requiring high tensile strength. Typical installation scenarios include machinery assembly, automotive components, equipment mounting, and structural fabrication where a partially threaded Grade 10.9 fastener is specified. It conforms to ASME B18.0.3.1M standards, making it appropriate for applications where dimensional consistency and material grade verification are required by engineering specifications or maintenance procedures.

Key Features

• Grade 10.9 steel construction for high tensile strength and reliable clamping performance
• Zinc-plated finish provides corrosion resistance in typical indoor and light outdoor environments
• Partially threaded shank allows precise clamping in bolted-joint and through-bolt applications
• M8 x 1.25 mm metric thread with 55 mm length under head to ASME B18.0.3.1M dimensional standards
• 13 mm hex head accepts standard metric sockets and box-end wrenches
• Sold in a pack of 10 to support small-batch service and assembly work

Compatibility

Designed as a standard metric replacement or service fastener for any assembly specifying an M8 x 1.25 x 55 mm Grade 10.9 partially threaded hex head cap screw conforming to ASME B18.0.3.1M.

Installation Notes

Installation is typically performed by mechanical technicians, millwrights, or equipment service personnel using a metric socket or combination wrench sized to 13 mm. Always de-energize and lock out equipment before replacing fasteners in electrical or mechanical systems. Apply appropriate thread lubricant or threadlocker per the equipment manufacturer's specifications, and torque to the value specified by the original equipment documentation for M8 Grade 10.9 fasteners. Inspect mating threads for damage or contamination before installation.
