Value Collection A996782 Shoulder Screw M5x0.80 Alloy Steel

Product Description

The VALUE COLLECTION A996782 is a metric shoulder screw manufactured from 12.9 grade alloy steel, designed for precision fastening applications that require a hardened, close-tolerance cylindrical shoulder. The shoulder measures 6 mm in diameter and 50 mm in length, with an M5x0.80 threaded end and a hex socket drive for installation with a standard hex key or Allen wrench. The head diameter ranges from 9.78 to 10 mm with a head height of 4.32 to 4.50 mm. This screw ships uncoated. It is suited for mechanical assemblies, tooling fixtures, and industrial equipment where a precise pivot, guide, or bearing surface is required.

Shoulder screws of this type are commonly used in industrial machinery, jigs, dies, and mechanical linkages where a hardened pin-like shaft must rotate freely or serve as a linear guide within a bushing or bearing. The 12.9 alloy steel grade provides high tensile strength, making this screw appropriate for demanding load-bearing and high-cycle applications in manufacturing and maintenance environments. Installation is typically performed by machinists, millwrights, or maintenance technicians.

Key Features

• 6 mm shoulder diameter with 50 mm shoulder length for precise pivot and guide applications
• M5x0.80 metric thread for secure clamping engagement
• 12.9 grade alloy steel construction for high tensile strength and hardness
• Hex socket drive compatible with standard metric Allen keys
• Uncoated finish suitable for use in clean, dry, or lightly oiled 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 mechanical assemblies, fixtures, and industrial equipment requiring an M5x0.80 threaded shoulder fastener with a 6 mm shoulder diameter.

Installation Notes

Installation is performed using a hex key sized for the socket drive. Ensure the mating bore or bushing is sized to match the 6 mm shoulder diameter for proper fit and function. De-energize and lock out any powered equipment before servicing assemblies containing shoulder screws. Do not exceed the design load limits for the 12.9 grade fastener, and avoid impact installation methods that could damage the shoulder surface.
