S-97188A225 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Superior thread-forming action creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• High-strength square drive provides superior torque transmission and reduces cam-out, ensuring reliable fastening and preventing tool slippage.
• Fully threaded pointed tip allows for easy starting and self-centering, enabling quick and precise alignment in sheet metal assemblies.
• Durable pan head design offers a low-profile, rounded finish that resists snagging and provides a neat appearance.
• Optimized for 0.025" maximum sheet thickness with a No. 32 drill bit (0.116" diameter), ensuring proper fit and maximum holding power in standard sheet metal.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets global industrial standards for hazardous substance restrictions.

Professional Applications & Engineering Value

This No. 6-18 thread forming screw is engineered to solve common fastening challenges in sheet metal applications, such as HVAC systems, electronic enclosures, and automotive panels. The 316 stainless steel material provides outstanding resistance to chlorides and acidic conditions, preventing rust and extending service life in demanding environments. Its thread forming design displaces material to create robust internal threads, eliminating the need for separate tapping operations and reducing assembly labor. The combination of a square drive and fully threaded pointed tip ensures quick starts and high torque capability, minimizing strip-outs and improving production efficiency. Ideal for industries requiring reliable, corrosion-resistant fasteners that maintain integrity under vibration and load.

Specification Summary & Compliance

This screw features a No. 6-18 thread size with a 1" length and Class 2A thread fit for standard industrial tolerances. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances. Manufactured to precise dimensions including a 0.27" head diameter and right-hand threading, it is designed for use with a No. 32 drill bit (0.116" diameter) in materials up to 0.025" thickness.
