S-91428A121 Length 5" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive woodworking environments.
• High-torque installation capability provided by the external hex head design, ensuring secure fastening without cam-out.
• Enhanced load distribution from the integrated flange, reducing the risk of wood surface damage and pull-through.
• Efficient thread-forming action creates strong, permanent threads in wood, eliminating the need for pre-drilling in many applications.
• Optimized thread engagement with a minimum 2.95" threaded length for maximum holding power in thick wood sections.
• Easy alignment and starting with a pointed tip, speeding up assembly times in production settings.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in industrial and construction projects.

Professional Applications & Engineering Value

This 316 stainless steel hex head wood screw is engineered to solve critical challenges in industrial wood fastening. The thread forming design displaces wood fibers rather than cutting them, creating a tighter, more vibration-resistant connection that prevents loosening in structural applications. The partially threaded shank allows the unthreaded portion to act as a precise dowel, maintaining alignment in timber construction and furniture assembly. With exceptional corrosion resistance from its 316 stainless steel composition, this screw withstands exposure to weather, chemicals, and moisture far better than standard steel fasteners. The external hex drive and flanged construction combine to provide superior clamping force distribution, making it ideal for heavy-duty wood-to-wood connections in construction, marine environments, and outdoor structures where durability is paramount.

Specification Summary & Compliance

This 1/4"-7 thread forming wood screw features standard inch measurements with a 5" length and 2.95" minimum thread engagement. The external hex drive (1/2" head width) ensures compatibility with standard industrial tools. Manufactured to precise dimensional standards for reliable performance in wood applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial and construction use.
