• Streamlined installation process using a standard 1/4" drill bit, reducing assembly time and tooling requirements

Professional Applications & Engineering Value

This 1/4"-20 UNC stainless steel press-fit stud is engineered to solve critical challenges in sheet metal assembly. Its 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, which is vital for electronics enclosures, automotive components, and outdoor equipment that face demanding environmental conditions. The press-fit design eliminates the need for welding or adhesives, allowing for a clean, high-strength installation into precisely drilled 0.249" holes. This prevents material distortion and maintains the integrity of thin-gauge sheets. The fully threaded, right-hand coarse thread (UNC) ensures maximum pull-out strength and vibration resistance, making it a reliable, permanent threaded insert for creating strong attachment points in panels and chassis where disassembly is not required.

Specification Summary & Compliance

This stud features a Class 2A thread fit per unified thread standards, ensuring dimensional accuracy and interchangeability. It is manufactured to precise specifications, including a base diameter of 0.352" and a thread length of 15/64". The product is RoHS 3 (2015/863/EU) Compliant, confirming it is free of hazardous substances and suitable for use in regulated electronic and industrial applications.
