S-94058A120 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Integrated sealing protection through stainless steel/rubber washer prevents leakage and provides vibration-resistant fastening
• Self-drilling capability with 1/4" drill tip eliminates pre-drilling requirements, reducing installation time and labor costs
• High-strength thread forming (BSD type) creates permanent, vibration-resistant threads in stainless steel and sheet metal
• Optimized installation control with external hex drive design allows for high torque application and secure fastening
• Maximum material penetration with 0.15" drilling capacity and fully threaded shank for consistent holding power
• Precision dimensional compliance with No. 10-16 thread specification ensures reliable interchangeability

Professional Applications & Engineering Value

This No. 10-16 thread forming screw delivers exceptional engineering value for stainless steel and sheet metal applications where moisture resistance and sealing integrity are critical. The zinc-plated 410 stainless steel construction provides superior corrosion protection while maintaining high tensile strength. The integrated stainless steel/rubber washer creates an immediate seal against environmental contaminants, making it ideal for HVAC systems, electrical enclosures, and outdoor equipment. The BSD thread forming design displaces material rather than removing it, resulting in stronger thread engagement and reduced loosening from vibration. With its self-drilling tip and external hex drive, this tapping screw eliminates multiple installation steps, significantly improving assembly efficiency in industrial manufacturing and metal fabrication operations.

Specification Summary & Compliance

This No. 10-16 x 3/4" tapping screw features precision thread forming with BSD specification, 16 threads per inch, and Class 2A thread tolerance for consistent performance. The fastener includes a flat washer configuration with 1/2" outer diameter and complies with industry standards for right-hand threaded, fully threaded fasteners. Manufactured from zinc-plated 410 stainless steel with stainless steel/rubber washer components, this product meets RoHS and REACH compliance requirements for industrial use.
