Cotter Pin 3/16 x 2-Inch Extended Prong – Hillman 381766 100-Pack

Description

Product Overview

The Hillman 381766 cotter pin is engineered to deliver dependable, repeatable performance across a broad spectrum of industrial and DIY applications. Measuring 3/16 by 2 inches, this straight‑shaped fastener features a distinctive bulb head that arrests movement, while one prong is deliberately extended to simplify insertion through pre‑drilled holes. Constructed from a high‑grade metallic finish, the pins resist corrosion and maintain structural integrity even under repeated loading cycles. The lightweight design—each pin weighs only 0.01 ounces—facilitates bulk handling without sacrificing strength. Packaged in a convenient 100‑piece box, the product is ready for immediate deployment in workshops, manufacturing floors, and field service environments. The combination of precise dimensions, extended prong geometry, and robust material composition makes these pins a versatile choice for securing components in machinery, agricultural equipment, and consumer‑grade hardware assemblies.

Usage

These cotter pins excel in scenarios where a quick, non‑threaded fastening method is required. In wood chippers and shredders, the extended prong allows technicians to insert the pin swiftly, while the bulb head ensures the pin remains seated, preventing accidental disengagement during high‑vibration operation. In agricultural machinery, such as balers and harvesters, the pins secure linkage pins and pivot points, delivering a reliable lock that can be released without tools when maintenance is needed. Hobbyists and DIY enthusiasts also benefit from the ease of use when assembling furniture, securing brackets, or reinforcing custom metal projects. The pins are compatible with standard 3/16‑by‑2‑inch holes, making them a drop‑in replacement for many legacy fasteners. Because no batteries or external power sources are required, the pins provide a low‑maintenance solution that reduces downtime and simplifies inventory management.

FAQ

What material are the cotter pins made from?

The pins are fabricated from a premium steel alloy with a protective metallic coating that offers corrosion resistance and maintains strength under load.

Can these pins be used in outdoor applications?

Yes, the corrosion‑resistant finish makes them suitable for outdoor equipment, agricultural machinery, and any environment where exposure to moisture is a concern.

How does the extended prong improve installation?

The longer prong provides a larger surface area for the installer to grip, allowing the pin to be guided into the hole more easily and reducing the chance of misalignment.

Are the pins reusable after removal?

While the pins are designed for permanent installation, they can be removed and reused if the bulb head has not been deformed. For critical safety applications, it is recommended to replace the pin after removal.

What is the best way to store the 100‑pack?

Store the pins in a dry, temperature‑controlled environment, preferably in the original packaging to protect the bulb heads from deformation and to keep the inventory organized.
