S-93285A212 M4 x 6 mm ASME B18.3.6M Set Screws

Key Features & Benefits at a Glance

• Vibration-resistant nylon tip prevents loosening under dynamic loads, ensuring long-term joint integrity.
• Corrosion-resistant 18-8 Stainless Steel construction provides excellent durability in harsh or humid environments.
• Precise Class 6g thread fit guarantees smooth installation and reliable engagement with mating components.
• Wide temperature tolerance (-50° to 250° F) maintains performance in extreme thermal conditions.
• Headless hex drive design (2 mm) allows for flush mounting and secure tightening in confined spaces.
• Coarse M4 x 0.7mm metric thread enables quick assembly and strong holding power.
• Soft green nylon tip protects shaft surfaces from marring and provides non-slip contact.

Professional Applications & Engineering Value

This M4 nylon tip set screw is engineered to solve critical industrial challenges like vibration-induced loosening and surface damage. The Nylon 6/6 plastic tip acts as a resilient locking element, absorbing shocks and maintaining clamp force without galling precision shafts or rotating components. Made from 18-8 Stainless Steel with a Rockwell B80 hardness, it resists corrosion while offering sufficient toughness for repeated adjustments. The hex drive and headless design make it ideal for set-and-forget applications in machinery, automotive assemblies, and electronic enclosures where space is limited and reliability is paramount. Its coarse thread ensures rapid installation, reducing assembly time in high-volume production.

Specification Summary & Compliance

This set screw features a Class 6g thread fit per ISO metric standards, with a nominal size of M4, a pitch of 0.7 mm, and a length of 6 mm. It is manufactured in compliance with ASME B18.3.6M for dimensional consistency and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances.
