Value Collection SCX204040-100BX M4x0.70 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION SCX204040-100BX is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, equipment fabrication, and maintenance applications. The screw features an M4 x 0.70 thread with a 40 mm length under head and is partially threaded, making it suitable for clamping applications where the unthreaded shank provides shear resistance. Manufactured from 18-8 austenitic stainless steel (Material Grade A2 per DIN 912), it offers reliable corrosion resistance in wet or chemically exposed environments. This box contains 100 pieces, sold as one unit.

This fastener is commonly used by machinists, millwrights, equipment technicians, and fabricators working on light mechanical assemblies, enclosures, fixtures, and instrumentation. The M4 size is typical in tight-clearance applications where a hex key drive allows fastening in recessed or obstructed locations. The DIN 912 standard ensures dimensional consistency for use in OEM and MRO replacement scenarios across a wide range of industrial and commercial equipment.

Key Features

• M4 x 0.70 metric thread — standard pitch for M4 fastener applications
• 40 mm length under head — accommodates moderate stack-up thicknesses
• Partially threaded shank — provides shear strength and accurate part alignment
• 18-8 stainless steel, Material Grade A2 — corrosion resistant in wet or mildly chemical environments
• Hex socket (Allen) drive — allows torquing in recessed or confined spaces
• Manufactured to DIN 912 standard — consistent dimensional tolerances across the lot

Compatibility

Designed as a DIN 912-compliant M4 x 0.70 hex socket cap screw suitable for use in any application requiring a standard metric M4 partially threaded fastener with a hex drive.

Installation Notes

Install using a correctly sized metric hex key or socket driver to avoid rounding the drive recess. De-energize or lock out any equipment before fastener replacement or disassembly per applicable safety procedures. Avoid overtightening stainless steel fasteners into stainless tapped holes without anti-galling compound, as galling can permanently seize the fastener. Verify thread engagement depth meets the requirements of the host material before final torque.
