Value Collection 537142PR Shoulder Screw M8x1.25 Alloy Steel

Product Description

The VALUE COLLECTION 537142PR is a metric shoulder screw machined from Grade 8 alloy steel, designed for precision fastening applications where a fixed-diameter shoulder controls spacing, alignment, or acts as a pivot or bearing surface. The shoulder measures 10 millimeters in diameter and 12 millimeters in length, with an M8x1.25 metric thread on the drive end. Drive engagement is through a hex socket, allowing installation with a standard hex key or Allen-type driver. This fastener is a standard choice for machinists, maintenance technicians, and mechanical assembly professionals working with metric hardware.

Shoulder screws of this type are used across a wide range of industrial and mechanical applications: linkage assemblies, jig and fixture construction, linear guide mounting, and pivot-point installations in machinery and tooling. The controlled shoulder diameter provides a precise bearing surface that standard cap screws cannot replicate. This part is suited for both light and moderate load applications in residential equipment, commercial machinery, and production tooling environments.

Key Features

• Grade 8 alloy steel construction for high tensile strength and durability
• 10 millimeter shoulder diameter provides accurate spacing and pivot control
• 12 millimeter shoulder length for defined bearing surface depth
• M8x1.25 metric thread standard for broad compatibility with metric hardware
• Hex socket drive for controlled torque application with standard hex keys
• Minimum order quantity of 5 units per order

Compatibility

Designed as a standard metric shoulder screw replacement or new-installation fastener for applications requiring a 10 millimeter shoulder diameter, 12 millimeter shoulder length, and M8x1.25 thread specification in alloy steel.

Installation Notes

Installation is performed by machinists or mechanical technicians using a properly sized hex key or Allen driver. Ensure the mating bore diameter matches the 10 millimeter shoulder for a correct fit before threading. De-energize and lock out any equipment before fastener replacement in live assemblies. Do not use an impact driver on hex socket shoulder screws, as this risks thread damage and loss of torque control.
