S-99795A101 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional holding power with 850 lbs shear strength and 490 lbs pull-out resistance for reliable performance in demanding concrete applications
• Superior corrosion protection from zinc-plated steel construction, extending service life in block, brick, and concrete environments
• Optimized installation efficiency with external hex drive design providing secure tool engagement and high torque transmission
• Engineered thread geometry with 2 5/8" thread length ensuring maximum engagement and holding capacity in masonry materials
• Removable design flexibility allowing for adjustments and disassembly without compromising structural integrity
• Precision installation compatibility with standard 5/16" drill bits and 1 1/2" minimum embedment depth for consistent performance
• Regulatory compliance assurance meeting RoHS 3 standards for environmental safety and international project requirements

Professional Applications & Engineering Value

Engineered for heavy-duty concrete fastening, these zinc-plated steel tapping screws solve critical challenges in construction and industrial applications. The external hex drive configuration delivers superior torque transmission during installation in 4,000 psi concrete, while the right-hand thread design with blunt tip ensures precise alignment and reduced installation stress. The 3/8" thread diameter combined with 2 5/8" thread length provides optimal load distribution in block, brick, and concrete substrates, preventing material failure under extreme shear and pull-out forces. These removable screws offer maintenance flexibility without sacrificing the 850 lbs shear strength required for structural connections, making them ideal for both permanent installations and applications requiring periodic access.

Specification Summary & Compliance

This 3/8" tapping screw features inch system measurements with right-hand thread direction and blunt tip design. The fastener demonstrates verified performance when tested in 4,000 psi concrete with specified installation parameters including 5/16" drill bit diameter and 1 1/2" minimum installation depth. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental compliance for international construction projects and industrial applications.
