S-97008A816 3/8"-16 x 1" Thumb Screws

Key Features & Benefits at a Glance

• Enhanced grip and torque application with a large 13/16" wide spade head, allowing for easy hand-tightening and removal without tools.
• Superior corrosion resistance from the zinc-plated steel construction, extending the screw's service life in various industrial environments.
• High mechanical strength and durability with a Rockwell B55 hardness and 40,000 psi tensile strength, ensuring reliable performance under load.
• Quick and easy installation thanks to the coarse UNC thread and Class 2A fit, providing smooth engagement and reduced cross-threading risk.
• Increased load distribution and stability from the integrated 0.688" flange, preventing the screw from pulling through softer materials.
• Versatile fastening capability with a fully threaded 1" length and right-hand direction, suitable for a wide range of assembly applications.
• Compliance with environmental and safety standards by being RoHS 3 compliant, meeting modern regulatory requirements.

Professional Applications & Engineering Value

This zinc-plated steel thumb screw is engineered to solve common industrial fastening challenges where tool-less access and high reliability are paramount. The flanged spade head design provides an excellent grip surface, reducing operator fatigue during frequent adjustments in machinery, access panels, and electronic enclosures. The UNC coarse thread and Class 2A thread fit ensure rapid assembly and disassembly while maintaining a secure hold, which is critical in maintenance-heavy environments. Made from robust steel with a Rockwell B55 hardness and 40,000 psi tensile strength, it withstands vibrational forces and repeated use without stripping or failing. Its fully threaded 1-inch length offers consistent clamping force, making it an ideal choice for securing components in automotive, manufacturing, and HVAC systems where durability and ease of use drive operational efficiency.

Specification Summary & Compliance

This thumb screw adheres to UNC coarse thread standards with a Class 2A thread fit, ensuring precise dimensional accuracy and interchangeability. The manufacturing conforms to standard industrial specifications for inch-series fasteners, with a thread size of 3/8"-16 and a thread diameter of 0.375". It is fully compliant with RoHS 3 (2015/863/EU), confirming the absence of restricted hazardous substances for safe use in global markets.
