Key Features & Benefits at a Glance
- Superior anti-rotation performance due to the ribbed neck design that prevents spinning during installation and under vibration
- Enhanced corrosion resistance provided by the zinc plating, extending the bolt's service life in demanding industrial environments
- High-strength reliability with a tensile strength of 70,000 PSI and SAE Grade 2 classification, ensuring dependable performance in heavy-duty applications
- Easy installation and removal with the slotted flat head design, compatible with standard hand tools for efficient maintenance
- Secure fastening in soft materials thanks to the wide flat head profile, which distributes load effectively and prevents pull-through
- Wide material compatibility from the coarse UNC 1/4"-20 thread, which provides excellent engagement in various substrates
- Regulatory compliance assurance meeting RoHS 3 and REACH standards, making it suitable for regulated industrial and commercial projects
Professional Applications & Engineering Value
This heavy-duty elevator bolt is engineered to solve critical fastening challenges in industrial settings. The zinc plated steel construction combats corrosion, while the ribbed neck provides exceptional resistance to rotation—a common failure point in conveyor systems, elevator assemblies, and machinery where components are subject to constant vibration. The fully threaded UNC coarse thread design ensures rapid installation and high pull-out strength in wood, plastics, and sheet metal. With a Rockwell B80 hardness and SAE Grade 2 strength rating, this bolt maintains integrity under dynamic loads, making it ideal for OEM manufacturing, material handling equipment, and assembly lines where reliability and compliance with REACH and RoHS 3 are mandatory.
Specification Summary & Compliance
This elevator bolt features a 1/4"-20 UNC coarse thread with Class 2A thread fit for standard tolerance and interchangeability. It complies with SAE Grade 2 mechanical properties, including 70,000 PSI tensile strength, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fastener is supplied with a nut and is manufactured to industrial standards for dimensional accuracy and performance consistency.
