S-93580A541 2-56 x 1/4" Steel Press-Fit Studs

Key Features & Benefits at a Glance

• Superior retention in sheet metal with precision press-fit design for 0.085" diameter holes, minimizing loosening in vibration-prone environments.
• Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in industrial settings.
• Easy installation with Class 2A thread fit provides smooth assembly and consistent engagement with mating components.
• Coarse UNC threading and right-hand direction enable quick fastening and disassembly for maintenance or adjustments.
• RoHS 3 compliance guarantees environmental safety and meets global regulatory standards for hazardous substances.
• Optimized for thin materials with a minimum 0.04" thickness requirement, ideal for lightweight sheet metal applications.
• Full threading along the 1/4" length offers maximum grip and load distribution across the entire stud.

Professional Applications & Engineering Value

This 2-56 UNC press-fit stud is engineered to solve common challenges in sheet metal assembly, such as thread stripping and component shift under stress. Made from zinc-plated steel, it resists rust and wear in harsh conditions, while the press-fit design ensures a secure, permanent hold in precisely drilled 0.085" holes—eliminating the need for additional adhesives or welding. The coarse UNC threading and Class 2A thread fit provide reliable engagement with nuts or tapped holes, reducing installation time and improving production efficiency in electronics enclosures, automotive panels, and machinery frames. Its full-threaded body distributes loads evenly, enhancing structural integrity in applications where space and weight are critical.

Specification Summary & Compliance

This stud adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It is designed for use with a No. 44 drill bit (0.085" hole diameter) and complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from restricted hazardous materials. The product meets industry specifications for press-fit fasteners, supporting reliable performance in standardized sheet metal assemblies.
