S-90433A160 5/16"-18 x 1 1/4" Elevator Bolts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for humid or chemically aggressive industrial environments.
• Superior anti-rotation and grip provided by the ribbed neck design, preventing the bolt from spinning during installation and in high-vibration applications.
• High-strength performance with a 100,000 psi tensile strength and Rockwell B80 hardness, ensuring reliable load-bearing capacity and durability.
• Easy installation and adjustment thanks to the coarse 5/16"-18 UNC threading and slotted flat head, allowing for quick assembly with standard tools.
• Complete fastening solution that includes a matching nut, saving procurement time and ensuring component compatibility.
• Regulatory peace of mind with full compliance to REACH and RoHS 3 standards, making it suitable for regulated markets and sustainable operations.
• Optimized for heavy-duty use in conveyor systems and elevator mechanisms where flat head profile and full threading provide a flush, secure fit.

Professional Applications & Engineering Value

This 18-8 Stainless Steel elevator bolt is engineered to solve critical challenges in material handling and industrial assembly. The ribbed neck is a key feature that bites into surfaces, effectively preventing rotation in high-torque or vibrating environments like conveyor belts and elevator systems. The flat head design sits flush, eliminating protrusions that could snag materials or pose safety hazards. Manufactured from corrosion-resistant stainless steel, it withstands exposure to moisture and harsh chemicals, significantly reducing maintenance frequency and replacement costs. The combination of coarse UNC threading and a fully threaded shank ensures a strong, reliable hold in a variety of substrates, making it a versatile and durable industrial fastener for demanding applications.
