Value Collection SCXX203030-050BX M3 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION SCXX203030-050BX is a partially threaded hex socket cap screw in M3 x 0.50 mm thread size with a 30 mm length under head. Manufactured from 316 stainless steel to Austenitic Grade A4, this fastener meets DIN 912 dimensional and material standards. The bright, uncoated finish preserves the natural corrosion resistance of 316 stainless, making it well suited for wet, chemical, or marine-adjacent environments. It is sold in a minimum box quantity of 50 pieces. Drive engagement is via a standard hex socket, compatible with metric hex key sets.

This screw is used across a wide range of trade and industrial applications where corrosion resistance and reliable clamping strength are required. Typical install scenarios include HVAC equipment panels, plumbing fixture mounting, electrical enclosures, and pool or water-treatment equipment assemblies. The M3 thread size fits small-clearance applications common in control panels and bracket hardware. The 30 mm under-head length accommodates moderate stack-up thickness while maintaining partial thread engagement for stronger shank support in shear-loaded joints.

Key Features

• M3 x 0.50 mm thread with 30 mm length under head for precise fitment in small hardware applications
• 316 stainless steel, Austenitic Grade A4 construction for superior corrosion resistance
• Partially threaded shank provides improved shear strength in clamped joints
• DIN 912 standard ensures dimensional interchangeability with compliant tooling and hardware
• Bright, uncoated finish maintains bare-metal corrosion resistance without added coating thickness
• Sold in a 50-piece box quantity suited for small-batch service work or stocking

Compatibility

Designed as a standard DIN 912 hex socket cap screw for use in any application requiring an M3 x 0.50 mm partially threaded fastener in 316 stainless steel.

Installation Notes

Installation is performed with a metric hex key or socket driver sized for M3 fasteners. Verify thread engagement and tapped hole depth before final torquing. As with all stainless fasteners, apply an appropriate anti-seize compound to reduce the risk of galling during installation. Power down or de-energize any equipment before accessing panels or enclosures where these screws are used.
