The VALUE COLLECTION HN4XX00500-100BX is an M5 x 0.80 metric hex nut manufactured from Grade 316 Austenitic Grade A4 stainless steel with a bright, uncoated finish. Conforming to DIN 934, this nut features a right-hand thread, 8 mm width across flats, and a 4 mm height. The 316 alloy provides strong resistance to corrosion, chlorides, and oxidizing environments, making it well suited for marine, chemical, and outdoor industrial applications. Sold in a minimum order quantity of 100 pieces per box, it is a standard fastener installed by millwrights, pipefitters, electricians, and general maintenance tradespeople across a wide range of assemblies.
This hex nut is used wherever an M5 x 0.80 metric fastener is required in corrosion-resistant applications. Typical install scenarios include stainless steel structural assemblies, marine hardware, pool and water treatment equipment, HVAC equipment frames, and plumbing fixture mounting. The DIN 934 standard ensures dimensional interchangeability with mating M5 x 0.80 bolts, screws, and studs sourced from any DIN-compliant manufacturer. The uncoated finish is compatible with systems where additional plating or coating is not required or would interfere with the mating thread tolerance.
Designed for use with any DIN-compliant M5 x 0.80 right-hand thread bolt, cap screw, or stud. Dimensional conformance to DIN 934 ensures fitment across metric fastener assemblies requiring an 8 mm across-flats hex nut at the M5 thread size.
Install and torque using a standard 8 mm open-end, box-end, or socket wrench. Apply appropriate anti-seize compound when joining stainless steel fasteners to prevent galling between mating threads. Always ensure the mating bolt or stud thread class is compatible with the nut before assembly. Follow applicable mechanical and structural codes for the torque specification required by the joint design.
