S-91746A312 10-24 x 3/4" Thumb Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Excellent manual grip and torque application thanks to the knurled round head design, reducing tool dependency and speeding up assembly
• High tensile strength of 80,000 psi ensures dependable load-bearing capacity and resistance to mechanical stress in demanding applications
• Precise and secure fastening with Class 2A thread fit and UNC coarse threading, providing consistent engagement and vibration resistance
• Low-profile head design allows for use in tight spaces while maintaining easy hand-adjustability
• Partial threading offers controlled engagement depth, preventing over-tightening and protecting sensitive components
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets international industry standards for hazardous substances

Professional Applications & Engineering Value

This 10-24 UNC thumb screw is engineered for applications requiring frequent adjustments and reliable hand-tightening without tools. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for electronics, machinery panels, medical devices, and outdoor equipment where moisture or chemicals are present. The knurled head texture ensures a non-slip grip, even with gloves or oily hands, reducing installation time and improving operator safety. With a low-profile round head and partial threading, it prevents cross-threading and allows precise positioning in assemblies with limited clearance. Its right-hand coarse thread and high Rockwell B83 hardness contribute to durability and repeated use without wear, addressing common issues of stripping and loosening in industrial settings.

Specification Summary & Compliance

This thumb screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy and interchangeability. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from restricted hazardous substances. Manufacturing specifications include a thread size of 10-24, length of 3/4", and partial threading up to 11/16", providing reliable performance in accordance with industrial fastener requirements.
