Value Collection HC3XX03006-050BX M3 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX03006-050BX is a metric hex head cap screw engineered for applications that demand corrosion resistance and dimensional consistency. Sized M3 x 0.50 with a 6 mm length under head, this fully threaded fastener is manufactured from Grade 316 austenitic stainless steel classified as Grade A4. The 5.5 mm hex drive and bright uncoated finish make it well-suited for clean, precise installations in wet, chemical-exposure, or outdoor environments. It conforms to DIN 933, EN 24017, and ISO 4017 standards, ensuring interchangeability with other metric fasteners built to those specifications. Machinists, field service technicians, and maintenance professionals working in HVAC, plumbing, electrical, and pool equipment applications rely on this type of fastener for secure, corrosion-resistant assembly.

This fastener is appropriate for light-duty metric assembly work in both residential and commercial settings. It is particularly useful in equipment enclosures, control panels, pool equipment housings, and plumbing fixture brackets where contact with moisture, chlorine, or mild chemicals is expected. The M3 thread size is common in small-frame equipment and instrumentation mounting. Grade A4 stainless steel provides superior corrosion performance compared to Grade A2 in harsh or submerged environments.

Key Features

• Fully threaded M3 x 0.50 metric thread for consistent engagement along the full fastener length
• Grade 316 austenitic stainless steel (Grade A4) for high corrosion resistance in wet and chemical environments
• Bright uncoated finish — no coating buildup to affect thread tolerance or fitment
• Conforms to DIN 933, EN 24017, and ISO 4017 standards for reliable metric interchangeability
• 5.5 mm hex drive compatible with standard metric hex wrenches and sockets

Compatibility

Designed as an OEM-style metric replacement fastener conforming to DIN 933, EN 24017, and ISO 4017 standards, suitable for any application calling out an M3 x 0.50 x 6 mm fully threaded hex head cap screw in Grade A4 stainless steel.

Installation Notes

Installation is performed by maintenance technicians and tradespeople using standard metric hand tools or power drivers with a 5.5 mm hex socket. Always confirm thread engagement is clean and free of debris before driving. Do not overtighten small-diameter metric fasteners — use a calibrated torque wrench when torque values are specified by the equipment manufacturer. When used in pool or chemical environments, inspect fasteners periodically for any signs of crevice corrosion at contact surfaces.
