S-93580A128 8-32 x 1 1/4" Steel Press-Fit Studs

Key Features & Benefits at a Glance

• Secure, vibration-resistant installations with a press-fit design that eliminates the need for welding or adhesives, reducing assembly time and labor costs.
• Superior corrosion resistance provided by the zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• Precise and consistent fit guaranteed by the tight hole size tolerance (0.000" to 0.003"), minimizing the risk of loose components and improving product quality.
• High-strength, coarse UNC threads (8-32) with a Class 2A fit enable quick and easy engagement with mating nuts for efficient high-volume assembly.
• Versatile 1-1/4" fully threaded length offers ample engagement for various material thicknesses, providing design flexibility and a reliable hold.
• Streamlined installation process using a standard No. 20 drill bit (0.161" diameter), reducing tooling complexity and inventory requirements.
• Compliance with environmental standards (RoHS 3), ensuring the studs are safe for use in regulated markets and electronics applications.

Professional Applications & Engineering Value

These 8-32 UNC press-fit studs are engineered to solve common challenges in sheet metal assembly, such as the need for strong, permanent threads without damaging thin materials. The zinc-plated steel construction provides excellent durability against corrosion, while the fully threaded design and Class 2A thread fit ensure reliable performance in high-vibration environments like electronics enclosures, automotive components, and machinery. The precise hole diameter (0.163") and tolerance control prevent stud rotation or push-out, reducing rework and enhancing the structural integrity of your assemblies. Ideal for automated production lines, these studs deliver consistent results and lower total cost of ownership.
