S-92670A635 1/4"-20 x 2 3/4" Elevator Bolts

Key Features & Benefits at a Glance

• Superior Anti-Rotation Performance: Square neck design prevents bolt spinning during installation and operation, ensuring secure fastening in high-vibration environments.
• Enhanced Corrosion Resistance: Zinc plating provides durable protection against rust and environmental degradation, extending service life in demanding industrial settings.
• Reliable Tensile Strength: SAE Grade 2 steel construction delivers 70,000 psi tensile strength, offering dependable load-bearing capacity for heavy-duty applications.
• Optimized Thread Engagement: Fully threaded 1/4"-20 UNC coarse spacing ensures maximum grip and easier alignment in various materials.
• Consistent Mechanical Properties: Rockwell B80 hardness maintains structural integrity under stress, reducing wear and deformation risks.
• Regulatory Compliance Assurance: REACH and RoHS 3 compliance guarantees safe, environmentally responsible use in regulated industries.
• Wide Flat Head Profile: Distributes clamping force evenly and sits flush with surfaces, minimizing protrusion in conveyor or elevator systems.

Professional Applications & Engineering Value

This fully threaded elevator bolt addresses critical industrial challenges where rotation prevention and consistent thread engagement are paramount. The square neck mechanically locks into mating parts, eliminating slippage in conveyor belts, elevator machinery, and material handling systems. Constructed from SAE Grade 2 steel with UNC coarse threading, it withstands dynamic loads while simplifying installation in wood, metal, or composite substrates. The zinc-plated finish combats moisture and chemical exposure in warehouses, manufacturing plants, or agricultural equipment. By combining 70,000 psi tensile strength with standardized Class 2A thread fit, this bolt ensures repeatable performance in assembly lines, reducing maintenance downtime and replacement costs.
