S-99663A453 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Enhanced torque transmission and tool compatibility through the external hex/slotted drive, allowing for high-tightening forces and versatile installation options.
• Secure, vibration-resistant fastening thanks to the thread forming tapping method, which creates strong threads in sheet metal without pre-tapping.
• Efficient, full-length engagement with fully threaded, pointed tip design for quick starts and consistent holding power across the entire 1" length.
• Increased load distribution and stability from the integrated flange, reducing the risk of surface damage and loosening under stress.
• Reliable performance in sheet metal up to 0.025" thickness, optimized with a 10 TPI thread pitch and 0.242" diameter for durable assemblies.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe, sustainable use in regulated industries.

Professional Applications & Engineering Value

These No. 14 flanged tapping screws are precision-engineered from 316 stainless steel to address common challenges in sheet metal assembly, such as corrosion, vibration loosening, and installation efficiency. The thread forming design eliminates the need for pre-tapped holes, reducing labor time and tooling costs while creating strong, reliable threads that resist back-out. With a fully threaded shank and pointed tip, these screws ensure rapid starts and full engagement in materials up to 0.025" thick, making them ideal for HVAC, automotive, and electronics enclosures. The external hex/slotted drive offers versatility for both power and manual tools, enhancing torque control and assembly speed in high-volume production environments.

Specification Summary & Compliance

This screw features a No. 14 size with a 0.242" thread diameter and 10 TPI right-hand threading, conforming to standard inch measurements for consistent fit. The flanged hex head (3/8" width, 0.24" height) and fully threaded round shank provide precise, Class 2A-equivalent tolerances. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), these screws meet stringent environmental and safety regulations for industrial use.
