Professional Applications & Engineering Value
This M20 thin hex nut with extra fine metric thread addresses critical engineering challenges in precision equipment and compact assemblies. The Black-Oxide 18-8 Stainless Steel construction provides superior corrosion protection while maintaining the mechanical strength required for demanding industrial applications. The reduced height profile enables weight savings and space optimization in machinery, automotive, and electronic enclosures where clearance is limited. The Class 6H thread fit ensures precise mating with corresponding bolts, minimizing play and maintaining clamping force in high-vibration environments. Manufactured to DIN 439B and ISO 4035 specifications, these metric thin nuts deliver consistent performance in automated assembly systems and maintenance operations worldwide.
Specification Summary & Compliance
This thin hex nut features M20 x 1.5 mm extra fine metric thread with Class 6H thread fit tolerance, manufactured according to DIN 439B and ISO 4035 standards. The external hex drive design provides 30mm across flats with 10mm height profile. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
