S-95195A120 1/4"-20 Hex Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant performance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
• Reliable left-hand threading prevents unintentional loosening in counter-rotating applications
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force
• Coarse UNC threading provides faster installation and better debris resistance
• Standard external hex design offers universal tool compatibility and high torque capability
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial use
• Dimensional consistency with 7/16" width and 7/32" height for predictable performance

Professional Applications & Engineering Value

This 1/4"-20 UNC left-hand hex nut delivers critical reverse-thread security in applications where standard right-hand fasteners would naturally loosen due to rotational forces. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these industrial nuts suitable for marine, automotive, and manufacturing environments where moisture and chemicals are present. The coarse thread spacing enables rapid installation while resisting jamming from debris or minor damage. With Class 2B thread fit precision, these left-hand thread fasteners maintain consistent engagement without binding, reducing assembly time and preventing cross-threading in high-volume production settings where reliability is paramount.

Specification Summary & Compliance

This inch system hex nut features 1/4"-20 UNC coarse threads with Class 2B thread fit tolerances per ASME standards. Dimensions include 7/16" width across flats and 7/32" height. The product is manufactured from 18-8 stainless steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
