Description
Product Overview
Hillman elevator bolts are precision-engineered fasteners designed for heavy-duty industrial applications. Constructed from high-strength alloy steel, these bolts meet Grade 2 hardness standards, providing exceptional durability and resistance to wear. The large diameter round head, also known as an elevator head, offers a broad bearing surface to prevent pull-through in soft materials. With a 5/16-18 UNC coarse thread, these bolts ensure quick and secure installation when used with matching nuts. Each bolt has a plain finish, measuring 1 inch in size with a 7.94-millimeter diameter, and is supplied in a convenient 100-piece package, making them ideal for bulk projects and maintenance tasks.

Usage
These elevator bolts are specifically designed for use in industrial and scientific settings, such as conveyor systems, machinery assembly, and elevator components. They are ideal for applications requiring a flush or low-profile fastener head that distributes load evenly, reducing the risk of material damage. Target users include maintenance professionals, mechanical engineers, and DIY enthusiasts working on equipment that demands reliable, high-strength fastening. The coarse UNC threads make them suitable for use with nuts in dynamic environments where vibration resistance is crucial.
