S-93878A831 10-32 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in steel, aluminum, brass, and cast iron without pre-tapping
• Maximum torque transmission through Phillips No. 2 drive and pan head design for secure installation and reduced cam-out
• Precise fine threading with UNF 10-32 specification ensures tight, secure fastening in thin materials and delicate applications
• Full-length threading provides consistent holding power along the entire 3/4" length for superior load distribution
• Right-hand thread direction offers standard installation compatibility with conventional driving tools and equipment
• Environmental compliance meets RoHS 3 and REACH regulations for safe use in regulated industries and global markets

Professional Applications & Engineering Value

These 10-32 thread forming screws deliver exceptional engineering value in metal fabrication and assembly operations. The zinc-plated steel construction provides reliable corrosion protection while the thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs. The UNF fine thread spacing ensures superior pull-out resistance in thin-section materials like sheet metal and delicate components. The Phillips No. 2 drive system combined with the pan head profile offers optimal torque transmission for high-volume assembly applications in steel, aluminum, brass, and cast iron substrates. These tapping screws solve common fastening challenges by providing consistent performance across multiple material types while maintaining thread integrity under vibration and dynamic loads.

Specification Summary & Compliance

Manufactured to precise dimensional standards with UNF 10-32 thread specification and fine thread spacing for superior fastening accuracy. Features a standard Class 2A thread fit for general industrial applications. The thread forming (SW) design creates mating threads in parent material without chip removal. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in regulated markets. Designed for use with #15 drill bit (0.18" diameter) for proper hole preparation in various metal substrates including steel, aluminum, brass, cast iron, and sheet metal applications.
