S-93585A514 M4 x 16 mm Thumb Screws

Key Features & Benefits at a Glance

• Tool-free installation and adjustment with knurled round head design for superior hand-tightening grip in confined spaces
• Exceptional corrosion resistance thanks to 18-8 stainless steel construction, ideal for humid or chemical environments
• High mechanical strength with 80,000 psi tensile strength and Rockwell B83 hardness for reliable load-bearing performance
• Precision thread engagement with Class 6g tolerance ensuring consistent fit and vibration resistance in assemblies
• Quick assembly efficiency through coarse M4x0.7mm threading that reduces installation time versus fine-pitch alternatives
• Full-threaded design provides maximum thread contact along the entire 16mm length for enhanced clamping force distribution
• Regulatory compliance ready meeting RoHS 3 and REACH standards for use in regulated industries and international exports

Professional Applications & Engineering Value

This M4 thumb screw delivers critical hand-operated fastening solutions for applications requiring frequent access or adjustment. The high-profile knurled head offers positive grip even with gloved hands, eliminating tool dependency in industrial maintenance panels, electronic enclosures, and machinery guards. Manufactured from 18-8 stainless steel, it resists oxidation and chemical degradation in harsh environments while maintaining 80,000 psi tensile strength. The Class 6g metric thread with coarse pitch ensures rapid installation and reliable thread engagement in aluminum extrusions and steel assemblies, reducing cross-threading risks during repeated operations. Its fully threaded 16mm length provides uniform stress distribution, making it ideal for vibration-prone equipment where consistent clamping force is paramount.

Specification Summary & Compliance

This thumb screw features M4x0.7mm coarse threads with Class 6g tolerance per metric standards, ensuring precise fit in tapped holes. The 16mm fully threaded length and right-hand threading conform to industrial fastening conventions. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing restricted substance compliance for global supply chains. The 12.7mm knurled round head with 9.5mm height provides standardized manual operation dimensions.
