- Flange diameter of 0.343" distributes clamping pressure evenly, protecting sensitive surfaces from damage.
Professional Applications & Engineering Value
This 10-32 UNF spade thumb screw is engineered to address common assembly challenges in electronics, machinery, and instrumentation. The 18-8 stainless steel construction resists oxidation and chemical exposure, making it ideal for environments where moisture or cleaning agents are present. Its flanged design eliminates the need for separate washers, reducing part count and speeding up installation in tight spaces. The fine UNF threads provide superior vibration resistance compared to coarse threads, ensuring stable performance in dynamic applications. With full threading along the 1/2" length, it maintains consistent grip depth across varying material thicknesses, while the spade head allows tool-free adjustments during maintenance cycles.
Specification Summary & Compliance
Manufactured to UNF thread standards with Class 2A thread fit for consistent dimensional accuracy. Features a 10-32 thread size with 0.19" thread diameter and fine thread spacing. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring hazardous substance restrictions are met. The screw is fully threaded with right-hand direction and includes a flange diameter of 0.343" for enhanced load distribution.
