Value Collection 537298BR Shoulder Screw M16x2 Alloy Steel

Product Description

The VALUE COLLECTION 537298BR is an alloy steel shoulder screw with a hex socket drive, built to metric thread and dimensional standards for precision mechanical assemblies. The shoulder diameter measures 20 millimeters and the shoulder length is 70 millimeters, providing a smooth, accurately ground bearing surface for rotating or sliding components. Thread size is M16x2 and the screw carries a material grade of 12.9, indicating high tensile strength suitable for demanding fastening applications. The uncoated finish leaves the base alloy steel exposed, making it appropriate for applications where coating buildup tolerance or subsequent surface treatment is a consideration. Machinists, tool-and-die technicians, and maintenance mechanics are the primary installers.

This shoulder screw is used in jigs, fixtures, dies, and precision machinery where a hardened, close-tolerance pivot or guide pin is needed. The 20-millimeter shoulder diameter and 70-millimeter shoulder length suit mid-range industrial assembly applications requiring controlled clearance fits. The M16x2 thread engages tapped holes in machine components following standard metric thread specifications. Applications span general manufacturing, tooling, and mechanical equipment maintenance in both production and job-shop environments.

Key Features

• 20 millimeter shoulder diameter provides a precise bearing surface for rotating or sliding fits
• 70 millimeter shoulder length accommodates deeper assemblies and thicker work pieces
• Material grade 12.9 alloy steel delivers high tensile and proof-load strength
• Hex socket drive allows installation with standard Allen keys or hex bit drivers in confined spaces
• Uncoated finish maintains tight dimensional tolerances without coating buildup
• Meets ASME/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 dimensional and performance standards

Compatibility

Designed as a metric shoulder screw for use in tapped M16x2 threaded holes in jigs, fixtures, dies, and general industrial machinery requiring a 20-millimeter shoulder diameter and 70-millimeter shoulder length to ISO 7379 specifications.

Installation Notes

Installation is performed by machinists or maintenance mechanics using an appropriately sized hex key or socket bit driver. Ensure the mating tapped hole is clean, properly threaded to M16x2, and free of debris before installation. Do not exceed the rated clamp load for grade 12.9 fasteners and verify the shoulder clearance fit with the mating bore before final assembly. Follow applicable machinery safety lockout procedures before servicing any assembly that includes this screw.
