S-90077A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
• Versatile installation options thanks to the combined Phillips/Slotted drive, accommodating various tools and reducing downtime.
• Efficient thread-forming design that creates strong, secure threads in sheet metal without pre-tapping, saving labor and material costs.
• Optimized pan head profile provides a low-profile, rounded finish for smooth surfaces and reduced snagging risks.
• Precise compatibility with No. 32 drill bits (0.116" diameter), enabling accurate hole preparation and maximum holding power.
• Full threading and pointed tip ensure quick starts and consistent engagement, speeding up assembly in high-volume applications.
• Compliance with global standards including RoHS 3 and REACH, guaranteeing safe, environmentally responsible use in regulated industries.

Professional Applications & Engineering Value

These No. 6 x 3/4" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and loose fasteners. The thread-forming A/AB type design displaces metal to create durable, vibration-resistant threads, eliminating the need for separate tapping operations and reducing assembly time. The Phillips/Slotted drive offers flexibility for both manual and powered tools, while the pan head ensures a flush fit that minimizes protrusion in tight spaces. Ideal for HVAC, automotive, and electronics enclosures, these screws provide reliable fastening solutions that withstand industrial stresses without compromising on RoHS and REACH compliance for worker and environmental safety.

Specification Summary & Compliance

This tapping screw features a No. 6 size with a 0.138" thread diameter and 18 TPI in a right-hand direction, fully threaded for consistent grip. Dimensions include a 3/4" length, 0.27" head diameter, and standard pan head profile, adhering to typical inch-system tolerances for precision. It is designed for use with a No. 32 drill bit (0.116" diameter) in materials up to 0.025" thickness, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are present in industrial applications.
