Description
Product Overview
Hillman elevator bolts are precision-engineered fasteners crafted from high-strength alloy steel, ensuring durability and reliability in demanding industrial environments. These bolts feature a black phosphate exterior finish that enhances corrosion resistance, making them suitable for indoor applications where moisture exposure is minimal. With a thread size of 1-1/4 inches and a diameter of 0.25 inches, they are designed for secure fastening in conveyor systems, machinery, and other equipment. The Grade 2 manufacturer grade provides a balance of strength and flexibility, while the hex head style allows for easy installation using standard tools. Key specifications include a flat head type for low-profile connections, UNC thread type for compatibility with nuts, and a right-hand thread style for straightforward tightening. Weighing 2.9 pounds per package, these bolts are built to withstand repeated use without compromising performance.
Usage
Hillman elevator bolts are ideal for conveyor systems in manufacturing, logistics, and agricultural settings, where they secure belts and components to prevent slippage and ensure smooth operation. They excel in applications involving soft materials like wood, plastic, or composite panels, as the large low head creates a flush, wide bearing surface that distributes pressure evenly. These bolts are commonly used by industrial maintenance teams, machinery assemblers, and DIY enthusiasts working on projects that require robust, non-rotating fasteners. Avoid using them in exterior or highly corrosive environments, as the plain steel construction is not intended for prolonged outdoor exposure. For best results, pair with compatible nuts and washers to achieve a tight, vibration-resistant fit in metal-based assemblies.
Why Choose Us
Hillman elevator bolts stand out due to their meticulous design and consistent quality, backed by the Hillman Group’s reputation for reliable industrial solutions. The square neck feature is a key advantage, preventing rotation during installation and use, which reduces the risk of loosening under dynamic loads. Unlike generic fasteners, these bolts undergo strict manufacturing controls to meet Grade 2 standards, ensuring uniform hardness and thread integrity. The black phosphate finish not only resists corrosion but also provides a matte appearance that blends seamlessly with industrial equipment. Customers benefit from a product that combines ease of use with long-term performance, minimizing downtime and maintenance costs in critical applications.

FAQ
What materials are these elevator bolts made from?
These bolts are constructed from alloy steel, which offers excellent strength and resistance to wear, making them suitable for heavy-duty applications in conveyor systems and machinery.
Can I use these bolts outdoors?
No, these bolts are not recommended for exterior use because the plain steel and black phosphate finish are designed for indoor environments where corrosion exposure is minimal.
How does the square neck prevent rotation?
The square neck fits into pre-drilled holes or slots in the material, locking the bolt in place during installation and use, which eliminates spinning and ensures a secure connection.
What is the thread size and type?
The thread size is 1-1/4 inches with UNC (Unified National Coarse) threads and a 2A thread class, providing reliable engagement with nuts for strong fastening.
Are these bolts compatible with all nuts?
Yes, the machine threads are standardized to work with most common nuts, but it’s advisable to use nuts of matching grade and size for optimal performance and safety.
