Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to fiberglass construction, ideal for harsh chemical or marine environments
- Excellent thermal stability with a wide operating range from -60°F to 190°F, ensuring reliable performance in extreme temperatures
- Enhanced load distribution from the integrated flange, reducing surface pressure and preventing material damage
- Quick and secure installation with the external hex drive and coarse UNC threads, allowing for high-speed assembly
- Precise thread engagement with Class 2A fit, providing consistent clamping force and vibration resistance
- Reduced part count as the flanged design often eliminates the need for a separate washer
- Environmental compliance assurance by meeting RoHS 3 standards, supporting sustainable manufacturing practices
Professional Applications & Engineering Value
This fiberglass hex head screw is engineered to solve critical challenges in demanding applications. Its non-conductive and non-corrosive properties make it indispensable in electrical enclosures, chemical processing equipment, and coastal structures where metal fasteners would fail. The partially threaded shank allows for precise clamping on specific sections, while the flange design increases bearing surface, preventing pull-through in soft or composite materials. The coarse UNC threadform ensures rapid installation and superior holding power in fiberglass, wood, and plastic substrates, significantly reducing assembly time and improving project efficiency in industrial maintenance and OEM manufacturing.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured with a gray fiberglass body, a 2 1/2" length, and a partial thread up to a minimum of 1 3/4". The product is fully RoHS 3 (2015/863/EU) Compliant, ensuring it meets strict environmental regulations for hazardous substance restrictions.
