S-93580A542 2-56 x 5/16" Steel Press-Fit Studs

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Reliable press-fit retention in 0.085" holes with precise diameter tolerance (0.000" to 0.003") ensuring vibration-resistant installations
• Full-length UNC coarse threading (2-56) provides maximum engagement strength and faster assembly compared to fine-thread alternatives
• Class 2A thread fit guarantees consistent mating with standard nuts and threaded components for simplified inventory management
• Optimized for thin materials with minimum 0.04" thickness requirement, ideal for sheet metal applications where space is limited
• Pre-engineered installation compatibility with standard No. 44 drill bits reduces tooling costs and setup time
• Environmental compliance assurance with RoHS 3 (2015/863/EU) certification for global manufacturing requirements

Professional Applications & Engineering Value

This zinc-plated steel press-fit stud solves critical challenges in sheet metal assembly where traditional fastening methods compromise structural integrity. The fully threaded 2-56 UNC design maintains consistent Class 2A thread fit across the entire 5/16" length, eliminating thread stripping in thin-gauge materials. Engineered for 0.085" hole diameters with tight tolerance control, it prevents rotation and pull-out in high-vibration environments common to industrial equipment, electronics enclosures, and automotive components. The right-hand coarse threading accelerates production line assembly while the zinc plating provides essential corrosion protection without requiring additional surface treatments.

Specification Summary & Compliance

Manufactured to precision standards with Class 2A thread fit per UNC specifications and 0.000" to 0.003" hole size tolerance for consistent press-fit performance. Complies with RoHS 3 (2015/863/EU) environmental directives and engineered for use with standard No. 44 drill bits (0.085" diameter). Suitable for minimum material thickness of 0.04" with 3/16" minimum edge distance requirements. PEM® part number FH-256-5 ensures traceability and quality consistency across production batches.
