Value Collection 537302BR Shoulder Screw M16x2 Alloy Steel

Product Description

The VALUE COLLECTION 537302BR is an alloy steel shoulder screw designed for precision mechanical assemblies requiring a hardened, close-tolerance cylindrical shoulder. The screw features a 20 mm shoulder diameter and an 80 mm shoulder length, with an M16x2 metric thread for secure fastening into tapped holes. The hex socket drive allows high-torque installation with a standard Allen key or hex bit driver. Built to material grade 12.9, this fastener delivers high tensile and yield strength suited to demanding industrial and machinery applications. It arrives uncoated, making it ready for installations where additional surface treatment is specified by the application.

This shoulder screw is used in applications where a precision pivot, guide pin, or linkage pin is needed within a machined assembly. Typical installations include jigs and fixtures, die sets, conveyor components, machine guards, and mechanical linkage systems. The 20 mm shoulder acts as a bearing surface or locating pin, while the M16x2 threaded end anchors into a receiving component. Maintenance machinists, tool and die makers, and industrial assembly technicians are the primary installers of this fastener type.

Key Features

• 20 mm shoulder diameter with 80 mm shoulder length for precise fit in bored or reamed holes
• M16x2 metric thread for compatibility with standard metric tapped assemblies
• Material grade 12.9 alloy steel for high tensile strength in load-bearing applications
• Hex socket drive allows installation in tight clearance environments using an Allen key or hex bit
• Uncoated finish suitable for post-treatment or direct use in dry or lightly lubricated environments
• 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 machined assemblies with M16x2 tapped receiving holes and bores sized to accept a 20 mm shoulder diameter per ISO 7379 and ASME/ANSI B18.3.3.M specifications.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a hex key or socket driver sized for the hex socket drive. Ensure the receiving bore is machined to the appropriate tolerance for a 20 mm shoulder diameter before installation. Do not exceed the rated torque for a grade 12.9 M16 fastener as specified in the applicable engineering standard for the assembly. Inspect thread engagement depth in the tapped hole to confirm full thread contact before torquing to final specification.
