S-91345A660 3/4"-10 x 1 1/2" Fiberglass Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance due to premium gray fiberglass construction, ideal for harsh chemical or marine environments.
• Reliable performance across extreme temperatures, maintaining integrity from -60°F to 190°F for versatile industrial applications.
• Secure and efficient installation with a standard external hex drive and 1-1/8" head width, compatible with common tools.
• Superior thread engagement and holding power from the coarse UNC thread and Class 2A fit, reducing the risk of cross-threading.
• Full-length threading ensures consistent grip and load distribution along the entire 1-1/2" length.
• Compliance with RoHS 3 regulations guarantees environmentally safe and sustainable material usage.
• Lightweight yet durable fiberglass material reduces overall weight without sacrificing mechanical strength.

Professional Applications & Engineering Value

Engineered for demanding environments, these fiberglass hex head screws provide a robust, non-conductive, and non-magnetic fastening solution. The coarse UNC thread design ensures quick assembly and high resistance to vibration loosening, making them ideal for electrical enclosures, chemical processing equipment, and structural components exposed to temperature fluctuations. The gray fiberglass material inherently resists corrosion, UV degradation, and chemical attack, eliminating the need for additional coatings and reducing long-term maintenance costs. With a temperature range of -60° to 190° F, they perform reliably in both freezing and moderately high-heat scenarios, offering a dependable alternative to metal fasteners where thermal expansion or electrical insulation is a concern.

Specification Summary & Compliance

This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent, precision-manufactured tolerances that facilitate smooth installation. Key dimensional specifications include a 3/4"-10 thread size, 1-1/2" length, 15/32" head height, and 1-1/8" head width. The product is fully threaded and features a right-hand thread direction. It is manufactured in compliance with RoHS 3 (2015/863/EU), ensuring it is free of hazardous substances and suitable for global industrial and commercial use.
