S-94650A413 1/4"-20 x 1 1/2" Elevator Bolts

Key Features & Benefits at a Glance

• Superior anti-rotation security with the integrated square neck design, preventing bolt spin during installation and under vibration.
• High-strength performance from SAE Grade 5 steel, ensuring reliable load-bearing capacity for demanding applications.
• Excellent corrosion resistance provided by the zinc yellow-chromate plating, extending service life in harsh industrial environments.
• Optimized for easy installation with a wide flat head profile and coarse UNC threading, reducing assembly time and effort.
• Consistent and reliable fit due to Unified Standard Class 2A thread fit, ensuring predictable performance in high-volume usage.
• Complete assembly solution as it includes a matching nut, streamlining procurement and reducing part count for B2B buyers.
• Compliance with major environmental regulations including REACH and RoHS 3, making it suitable for global supply chains.

Professional Applications & Engineering Value

This Grade 5 steel elevator bolt is engineered to solve critical challenges in material handling and machinery assembly. The square neck design is pivotal, locking securely into mating parts to prevent rotation—a common failure point in conveyor systems, elevator platforms, and heavy equipment where vibration is constant. Its fully threaded 1/4"-20 UNC body and coarse thread spacing allow for deep engagement and rapid installation, even in applications with limited access. The combination of 120,000 psi tensile strength and Rockwell C25 hardness ensures it can withstand significant shear and tensile stresses without deforming. The zinc yellow-chromate finish adds a durable barrier against moisture and chemicals, making it a reliable choice for industrial and outdoor settings where corrosion would otherwise lead to premature maintenance and downtime.

Specification Summary & Compliance

This elevator bolt adheres to Unified Standard Class 2A thread fit for consistent dimensional accuracy. It is manufactured to SAE Grade 5 strength specifications with a tensile strength of 120,000 psi. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring it meets stringent environmental and safety standards for industrial use worldwide.
