Value Collection 44059 Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 44059 is a metric hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 12.9 steel to ISO 12.9 standards, this screw delivers exceptional tensile strength suitable for demanding load-bearing connections. The M8 x 1.25 thread profile with a 50 mm length under head provides reliable clamping force across a range of joint thicknesses. A zinc-plated finish offers basic corrosion resistance for general-purpose use. The partially threaded shank allows the unthreaded portion to bear shear loads, making it well-suited for precision-fit bolted joints. Licensed fastener technicians, millwrights, and maintenance mechanics are the typical installers of this hardware.

This screw is suited for metric-standard assemblies in manufacturing equipment, automotive components, machinery frames, and fabricated steel structures. The M8 thread size and 50 mm under-head length make it a common fit for mid-sized fastening applications where a full-thread screw would reduce shear capacity. Sold in packages of 50 units, making it practical for production line use or service shop inventory. It is appropriate for both original equipment assembly and maintenance replacement scenarios where a Grade 12.9 metric fastener is specified.

Key Features

• Grade 12.9 steel construction meets ISO 12.9 standards for high tensile and proof load performance
• Partially threaded shank improves shear load distribution in precision bolted joints
• M8 x 1.25 metric thread with 50 mm length under head for mid-range clamping depth
• 13 mm hex drive size compatible with standard metric wrenches and sockets
• Zinc-plated finish provides basic corrosion resistance for general-purpose environments
• Packaged in quantities of 50 for efficient shop or production use

Compatibility

Designed as a standard metric replacement or production fastener for assemblies specifying an M8 x 1.25 x 50 mm partially threaded hex head cap screw to ISO 12.9 grade requirements.

Installation Notes

Installation should be performed by qualified mechanics or technicians familiar with metric fastener specifications and proper torque procedures. Always consult the equipment manufacturer torque specification chart for Grade 12.9 M8 fasteners before final tightening. Use a calibrated torque wrench and the appropriate 13 mm hex socket or open-end wrench. Ensure mating threads are clean and free of debris before installation to avoid galling or false torque readings.
