Value Collection 537078PS Shoulder Screw M5x0.8 Alloy Steel

Product Description

The VALUE COLLECTION 537078PS is an alloy steel shoulder screw with a metric M5x0.8 thread and hex socket drive. The precision-ground shoulder measures 6 millimeters in diameter and 16 millimeters in length, providing the accurate bearing surface and standoff distance that shoulder screws are selected for. The fastener carries a material grade of 12.9, indicating a high-strength alloy steel construction left uncoated. Machinists, toolmakers, and assembly technicians use this type of shoulder screw as a pivot pin, guide pin, or linear motion locating element in fixtures, dies, and precision assemblies.

This shoulder screw is suited for industrial and manufacturing applications where a hardened, close-tolerance cylindrical shoulder is required. Common use cases include die sets, stamping fixtures, jigs, linkage pivot points, and machine sub-assemblies that need a reliable, repeatable locating element. The hex socket drive allows installation in tight clearance areas using a standard hex key. It is applicable in both light industrial and heavy manufacturing environments.

Key Features

• 6 millimeter precision shoulder diameter provides accurate bearing and locating surface
• 16 millimeter shoulder length suits standard fixture and die applications
• M5x0.8 metric thread for secure fastening per metric thread standards
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Hex socket drive enables installation in confined spaces with a hex key
• Uncoated finish suitable for use as-supplied or with added lubrication or coating in the field

Compatibility

Designed as an OEM-style replacement or direct-use shoulder screw for metric tooling, fixtures, and precision assemblies requiring a 6 millimeter shoulder diameter and M5x0.8 thread per ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards.

Installation Notes

Installation should be performed by a qualified machinist or assembly technician familiar with metric fastener torque practices. Ensure the mating bore diameter is machined to the correct tolerance for a 6 millimeter shoulder before installation. Use the appropriate hex key to drive the socket head and do not exceed the torque capacity of the M5 thread. De-grease mating surfaces when precise shoulder seating is required.
