S-93580A568 5/16"-18 x 1" Steel Press-Fit Studs

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments.
• Exceptional pull-out resistance in sheet metal, designed for a precise 0.311" hole diameter to ensure a secure, permanent fit.
• Reliable and easy assembly with fully threaded, right-hand UNC coarse threading for quick installation and high resistance to vibration loosening.
• Guaranteed dimensional accuracy with Class 2A thread fit, providing consistent performance and interchangeability in high-volume production.
• Optimized for thin materials, requiring a minimum material thickness of only 0.093", ideal for lightweight sheet metal assemblies.
• Simplified installation process using a standard N drill bit (0.302" diameter), reducing preparation time and tooling costs.
• Compliance with global environmental standards, being RoHS 3 compliant for use in regulated markets and sustainable manufacturing.

Professional Applications & Engineering Value

This zinc-plated steel press-fit stud is engineered to solve common challenges in sheet metal applications, such as maintaining secure fastening in thin materials prone to vibration and stress. The fully threaded design with 5/16"-18 UNC coarse threading ensures high clamp load distribution, preventing failure in dynamic environments. Its precise press-fit installation into a 0.311" hole, combined with a Class 2A thread fit, eliminates the need for additional locking mechanisms, reducing assembly time and cost. The zinc plating provides a protective barrier against corrosion, making it ideal for electronics enclosures, automotive panels, and industrial machinery where durability and RoHS 3 compliance are critical for long-term reliability.
