Key Features & Benefits at a Glance
- Superior tensile strength of 110,000 psi ensures reliable performance in demanding applications, preventing fastener failure under high stress.
- Enhanced corrosion resistance from the zinc-plated steel coating prolongs service life in harsh industrial environments.
- Precise Class 3A thread fit guarantees tight, secure connections with minimal risk of loosening or cross-threading.
- Integrated flange design distributes load evenly, eliminating the need for a separate washer and speeding up assembly.
- High hardness rating (Rockwell C25) provides excellent wear resistance and durability against repeated use.
- Fully threaded UNF fine spacing offers maximum grip and holding power in materials requiring fine thread engagement.
- External hex drive allows for easy installation and removal with standard tools, improving workflow efficiency.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 5 hex head screw addresses critical assembly challenges with its robust zinc-plated steel construction and UNF fine thread design. The combination of 110,000 psi tensile strength and Class 3A thread fit ensures secure, vibration-resistant fastening in machinery, automotive, and structural components, reducing maintenance needs. The flange head enhances stability by providing a larger bearing surface, ideal for applications where space is limited but high clamp load is required. This screw is a reliable choice for engineers seeking durability, compliance, and performance in inch system assemblies.
Specification Summary & Compliance
This screw meets Class 3A thread fit tolerances for precision and is manufactured in accordance with IFI 111 / SAE J429 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industries. Key dimensions include a 10-32 UNF thread size, 3/4" length, and 29/64" flange diameter, providing consistent performance and interchangeability.
