• Full-length 31/64" threading providing maximum engagement depth and load distribution across materials
• Optimized for thin materials with 0.04" minimum thickness requirement, ideal for sheet metal assemblies
• Right-hand coarse UNC threads enabling quick installation and high resistance to vibration-induced loosening
• RoHS 3 compliance meeting international environmental standards for electronics and regulated industries

Professional Applications & Engineering Value

This zinc-plated steel press-fit stud solves critical retention challenges in sheet metal assemblies where traditional fastening methods fail. The 2-56 UNC coarse threading combined with Class 2A thread fit ensures reliable performance in vibration-prone applications while the press-fit design eliminates the need for secondary locking mechanisms. Engineered specifically for 0.085" diameter holes in materials as thin as 0.04", this fully threaded stud provides maximum pull-out resistance in electronics enclosures, automotive components, and industrial control panels. The zinc plating offers essential corrosion protection while maintaining electrical conductivity, making it ideal for grounding applications and EMI shielding requirements.
