Value Collection 532501PR M1.6 Hex Socket Cap Screw Alloy Steel

Product Description

The VALUE COLLECTION 532501PR is an M1.6 x 0.35 metric hex socket cap screw designed for precision fastening applications that require a low-profile, high-strength connection. It measures 3 mm in length under the head and is fully threaded along that length. Manufactured from alloy steel at a material grade of 12.9, it delivers high tensile and yield strength relative to its small size. The black oxide finish provides a degree of corrosion resistance and reduces light reflection, making it suitable for both functional and low-visibility installations. This fastener is installed by machinists, maintenance technicians, and precision assembly professionals.

This screw is suited for tight-clearance assemblies where a standard hex head would not fit. Common applications include instrument housings, small machinery, electronics enclosures, optical mounts, and precision mechanical assemblies. The M1.6 thread size places it in the micro-fastener category, typically used where space constraints rule out larger hardware. This part ships in a minimum order quantity of 100 pieces.

Key Features

• M1.6 x 0.35 metric thread, fully threaded to the head
• 3 mm length under head for shallow-clearance fastening
• Alloy steel construction, material grade 12.9 for high tensile strength
• Black oxide coating for mild corrosion resistance and reduced reflectivity
• Hex socket drive for use with standard Allen or hex key tools
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant metric hex socket cap screw, suitable for M1.6 x 0.35 threaded holes in precision assemblies and small mechanical components.

Installation Notes

Installation requires an appropriately sized hex key or Allen driver sized for M1.6 socket cap screws. Always confirm the receiving thread is clean and free of debris before driving. Avoid over-torquing, as micro-fasteners at this size are susceptible to thread stripping even at grade 12.9. This fastener should be installed by qualified machinists or technicians familiar with metric micro-fastener assemblies.
