Value Collection 537258BR Shoulder Screw M12x1.75

Product Description

The VALUE COLLECTION 537258BR is an alloy steel shoulder screw with a metric M12x1.75 hex socket drive, designed for precision fastening applications where a smooth bearing shoulder is required. The 16 mm shoulder diameter and 60 mm shoulder length provide a controlled pivot or bearing surface, while the Grade 12.9 alloy steel construction delivers high tensile strength. The uncoated finish is suited for applications where surface coating is unnecessary or where a secondary treatment will be applied. This screw is installed by maintenance technicians, machine builders, and industrial service professionals.

This shoulder screw is used in mechanical assemblies, jigs, fixtures, and machine components where a close-tolerance cylindrical shoulder is needed to locate or guide moving parts. The hex socket drive allows installation with a standard Allen key or hex bit in confined spaces. It meets ASME/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 dimensional and performance standards, making it appropriate for both OEM manufacturing and field replacement work across general industrial and trade applications.

Key Features

• Grade 12.9 alloy steel construction for high tensile and shear strength
• 16 mm shoulder diameter with 60 mm shoulder length for precision bearing and pivot applications
• M12x1.75 metric thread for secure clamping engagement
• Hex socket drive for torque application in tight or recessed spaces
• Uncoated finish compatible with secondary surface treatments
• Meets ASME/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 standards

Compatibility

Designed as a standard metric shoulder screw for use in mechanical assemblies, fixtures, and equipment requiring an M12x1.75 threaded fastener with a 16 mm precision shoulder.

Installation Notes

Installation is performed with an appropriate hex key or Allen socket sized for the drive. Ensure mating bores are correctly sized to accept the 16 mm shoulder diameter for proper fit and function. Disengage or de-energize equipment fully before removing or replacing fasteners in operational machinery. Do not exceed the torque capacity of the Grade 12.9 fastener or the mating material.
