S-94058A110 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
• Efficient self-drilling installation with integrated No. 2 drill tip that eliminates pre-drilling in materials up to 0.098" thick
• Reliable sealing performance through the integrated stainless steel/rubber washer that prevents leakage and loosening
• Strong thread-forming capability with BSD tapping design that creates durable, vibration-resistant threads in stainless steel and sheet metal
• Easy installation and removal with external 1/4" hex head design for secure tool engagement and high torque application
• Full-length threading ensures maximum grip and load distribution along the entire 3/4" fastener length
• Precise dimensional consistency with No. 8 size (0.164" diameter) and 18 TPI for reliable, interchangeable fastening solutions

Professional Applications & Engineering Value

This heavy-duty No. 8 tapping screw delivers exceptional engineering value for professionals working with stainless steel and sheet metal applications. The zinc-plated 410 stainless steel construction provides enhanced corrosion resistance, making it ideal for outdoor equipment, marine components, and industrial machinery exposed to moisture and chemicals. The thread forming BSD design creates strong, permanent threads without chip removal, eliminating contamination risks in sensitive assemblies. With its integrated sealing washer and self-drilling tip, this fastener streamlines installation while providing reliable protection against vibration loosening and environmental ingress. The combination of external hex drive and fully threaded design ensures maximum clamping force and pull-out resistance, making it a superior choice for structural fastening where reliability is critical.
