Value Collection 537152PS Shoulder Screw M8x1.25

Product Description

The VALUE COLLECTION 537152PS is an alloy steel shoulder screw with a metric M8x1.25 thread and hex socket drive. The shoulder measures 10 mm in diameter and 30 mm in length, providing a precision cylindrical bearing surface used for alignment, pivoting, and linkage applications in mechanical assemblies. The head diameter ranges from 15.73 to 16 mm with a head height of 6.78 to 7 mm. Material grade is 12.9, indicating a high-strength fastener suited for demanding load conditions. The uncoated finish leaves the alloy steel surface bare. This fastener is installed by machinists, maintenance technicians, and industrial assemblers working with jigs, fixtures, cams, and rotating or sliding components.

This shoulder screw is used wherever a close-tolerance shaft or pivot point is needed within a mechanical assembly. Typical applications include die sets, sheet metal fabrication tooling, machine guarding linkages, and fixture plates in manufacturing environments. The hex socket drive allows installation in confined spaces using a standard hex key or Allen wrench. The M8x1.25 metric thread is sized for standard metric-tapped receiver holes. Suitable for both light and heavy industrial use where precision alignment and consistent bearing surface geometry are required.

Key Features

• 10 mm shoulder diameter provides a precision bearing and alignment surface
• 30 mm shoulder length suits medium-depth pivot and linkage assemblies
• Grade 12.9 alloy steel delivers high tensile and proof load strength
• Hex socket drive allows torquing in tight or recessed installations
• M8x1.25 metric thread conforms to standard metric fastener specifications
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards

Compatibility

Designed as a standard metric shoulder screw for use in mechanical assemblies requiring an M8x1.25 threaded receiver and a 10 mm shoulder diameter bore or bushing.

Installation Notes

Installation is performed by machinists or maintenance technicians using a hex key sized for the socket drive. Before installation, verify the receiver thread is clean and undamaged and that the bore or bushing diameter matches the 10 mm shoulder. Do not over-torque the threaded section, as grade 12.9 fasteners are high-strength but the shoulder geometry can be compromised by lateral loading if the fit is incorrect. Follow applicable industry standards and equipment manufacturer specifications for fastener seating depth and preload.
