Value Collection HC3XX04016-050BX M4 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION HC3XX04016-050BX is a fully threaded hex head cap screw manufactured to DIN 933 standards. It features an M4 x 0.70 metric thread with a 16 mm length under head. The fastener is machined from Grade 316 austenitic stainless steel, designated Stainless Steel Grade A4, offering strong resistance to corrosion and oxidation in wet, chemical, and marine environments. The bright, uncoated finish maintains dimensional precision for applications requiring close-tolerance fitment. Licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance crews routinely spec this grade of fastener where mild steel or 304 stainless would be insufficient.

This screw is well-suited for plumbing fixture mounting, HVAC equipment assembly, pool and spa hardware, and any mechanical application exposed to moisture, chlorine, or mild acids. The M4 thread size and 16 mm shank length fit compact fastening points common on equipment panels, pipe hangers, junction boxes, and pump housings. The minimum order quantity is 50 pieces per order, and each package contains 1 piece, making this appropriate for maintenance stock or specific repair applications requiring the full 50-unit lot.

Key Features

• Grade 316 austenitic stainless steel for superior corrosion resistance in chlorinated and salt-water environments
• Fully threaded shank for maximum thread engagement over the entire 16 mm length
• DIN 933 standard compliance ensures consistent dimensional interchangeability
• 7 mm hex drive compatible with standard metric hex wrenches and sockets
• Bright uncoated finish maintains precise dimensions with no coating buildup on threads
• Minimum order quantity of 50 units supports maintenance inventory stocking

Compatibility

Designed as a standard DIN 933 metric hex head cap screw with M4 x 0.70 thread, compatible with any M4 x 0.70 tapped hole or metric nut conforming to DIN or ISO metric thread specifications.

Installation Notes

Installation is performed by licensed tradespeople or qualified maintenance technicians using standard metric hand tools or power drivers with appropriate torque control. Always de-energize or isolate equipment before fastening near electrical or pressurized components. Verify thread engagement depth and mating material compatibility before driving. Grade 316 stainless fasteners may gall when run against stainless mating threads — applying an anti-seize compound is standard practice in the trade to prevent thread seizure.
