Value Collection 532040PR M4x0.70 Hex Socket Cap Screw 45mm

Product Description

The VALUE COLLECTION 532040PR is a partially threaded hex socket cap screw engineered for high-strength mechanical fastening applications. It features an M4 x 0.70 thread profile with a 45 mm length under head. The fastener is machined from alloy steel to material grade 12.9, placing it among the highest strength classes for metric fasteners. A black oxide finish provides moderate corrosion resistance and reduces light reflection in service environments. This screw is installed using a hex key or Allen driver and is suited for precision assemblies where high clamping force in a compact head profile is required.

This screw is used across a broad range of industrial, mechanical, and equipment assembly applications. Grade 12.9 alloy steel construction makes it appropriate for high-load joints in machinery, jigs, fixtures, tooling, and structural components where standard hardware grades are insufficient. It conforms to DIN 912 and ISO 898-1 standards, making it a direct fit in metric fastener applications specifying those designations. The black oxide finish suits indoor or low-moisture environments. This item is sold individually but carries a minimum order quantity of 100 pieces per order.

Key Features

• M4 x 0.70 thread size with 45 mm length under head for deep engagement in fastened assemblies
• Grade 12.9 alloy steel construction delivers high tensile and proof load strength
• Partially threaded shank allows shoulder-bearing loads in close-tolerance bores
• Black oxide coating provides mild corrosion protection and low-reflectance appearance
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket drive accepts standard metric Allen keys or hex bit drivers

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any application specifying an M4 x 0.70 partially threaded socket cap screw to ISO 898-1 grade 12.9.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician using a properly sized metric hex key or socket bit to avoid rounding the drive recess. Always verify thread engagement depth and confirm the receiving thread is tapped to M4 x 0.70 before torquing. Do not exceed the rated proof load for grade 12.9 hardware; consult engineering fastener tables for torque specifications appropriate to your joint design. Minimum order quantity of 100 pieces applies per order transaction.
