Value Collection BDNA-A410017 Hex Cap Screw M5x0.80x20mm 316 Ss

Product Description

The VALUE COLLECTION BDNA-A410017 is a metric hex head cap screw sized M5 x 0.80 x 20 mm, manufactured from Grade 316 Austenitic Grade A4 stainless steel with a bright, uncoated finish. It is fully threaded along the entire shank length and conforms to DIN 933. The 8 mm hex drive allows installation with standard metric wrenches or hex sockets. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, making this fastener suitable for demanding environments where standard carbon steel hardware would degrade. Licensed tradespeople and maintenance professionals working in corrosion-prone or sanitary applications rely on this material grade for reliable, long-service fastening.

This screw is used across a wide range of trade and industrial applications where metric fasteners and corrosion resistance are required. Common installation scenarios include HVAC equipment assembly, plumbing fixture mounting, pool and spa equipment enclosures, marine environments, food-service equipment, and general mechanical assemblies exposed to moisture or chemicals. The fully threaded design provides maximum thread engagement across the full shank, which is advantageous in thin-material applications or when threading directly into a tapped hole without a nut.

Key Features

• Grade 316 Austenitic Grade A4 stainless steel for superior corrosion resistance
• Fully threaded shank per DIN 933 standard for maximum thread engagement
• M5 x 0.80 mm thread pitch with 20 mm length under head
• 8 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no risk of coating interference with thread fit or torque values
• Metric thread standard suitable for OEM, MRO, and field repair use

Compatibility

Designed as a DIN 933 compliant metric hex head cap screw for use in any application requiring an M5 x 0.80 thread pitch fastener in Grade 316 stainless steel.

Installation Notes

Installation should be performed with a properly sized metric wrench or socket to avoid rounding the hex drive. Verify thread engagement depth and tapped hole condition before final torque. When installing stainless steel fasteners into stainless or aluminum tapped holes, apply an appropriate anti-seize compound to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
