Value Collection A996727 Hex Socket Cap Screw M3x0.50 25pk

Product Description

The VALUE COLLECTION A996727 is a partially threaded hex socket cap screw designed for precision fastening applications in mechanical assemblies, tooling, and equipment maintenance. Built to DIN 912 and ISO 898-1 standards, this M3 x 0.50 screw features a 50 mm length under head and is manufactured from alloy steel at material grade 12.9 — the highest common strength class for metric socket cap screws. The black oxide finish provides mild corrosion resistance and reduces light reflection in close-tolerance assemblies. This package contains 25 pieces, suitable for stocking or small-batch use.

This screw is used in applications where high clamping force is needed in a compact fastener footprint. The M3 x 0.50 thread size and 50 mm under-head length make it well suited for light machinery, fixtures, jigs, pneumatic components, and precision enclosures. The hex socket drive accepts a standard hex key or Allen driver, making it accessible in tight clearance areas where a wrench cannot fit. Machinists, millwrights, maintenance technicians, and equipment assemblers are the typical installers.

Key Features

• M3 x 0.50 thread with 50 mm length under head for deep engagement in thick stock
• Grade 12.9 alloy steel construction for maximum tensile and proof load strength
• Partially threaded shank provides a shoulder bearing surface for precise alignment
• Black oxide finish reduces surface corrosion and light glare
• Hex socket (Allen) drive for use in confined or recessed mounting locations
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style or maintenance replacement metric socket cap screw for machinery, fixtures, and equipment assemblies requiring an M3 x 0.50 partially threaded fastener conforming to DIN 912 geometry and ISO 898-1 mechanical property requirements.

Installation Notes

Install and remove using a correctly sized metric hex key or Allen driver to avoid rounding the socket recess. De-energize and lock out any equipment before replacing fasteners in live assemblies. Grade 12.9 fasteners should not be substituted with lower-grade hardware in torque-critical joints. Follow applicable equipment manufacturer torque specifications and relevant industry standards for the assembly type.
