Value Collection 532016P M3x0.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532016P is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and equipment fabrication. Sized at M3 x 0.50 with a 25 mm length under head, this fastener is partially threaded and driven by a hex socket tool. Constructed from grade 12.9 alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance in a compact form factor. Sold individually with a minimum order quantity of 100 units, it is well suited for production-volume procurement.

This fastener is used in applications requiring high-strength metric fastening in tight clearances where a hex socket drive is preferred over an external hex head. Common applications include machine tool assemblies, jigs and fixtures, hydraulic manifolds, and precision mechanical equipment. The partially threaded shank provides clearance fit engagement through stacked components before threading into the tapped receiving material. Mechanical contractors, millwrights, and fabrication shops are the primary installers of this fastener type.

Key Features

• M3 x 0.50 thread size with 25 mm length under head for precise dimensional control
• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank allows accurate component alignment before engagement
• Hex socket drive enables installation in recessed or confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric hex socket cap screw per DIN 912, compatible with M3 x 0.50 tapped holes in metallic and rigid substrates requiring a grade 12.9 high-strength fastener.

Installation Notes

Installation requires a properly sized hex socket driver or Allen key matched to the M3 socket head. The receiving hole must be tapped to M3 x 0.50 and cleared of debris before fastener engagement. Power down or de-energize any equipment before accessing internal fastener locations. Do not exceed the rated clamp load for grade 12.9 hardware by using impact drivers without torque control on small-diameter metric screws.
