Hillman 300324 3/4 In.Split Lock Washer Grade 8, 20-Pack

Description

Product Overview

The Hillman 300324 split lock washer is engineered for demanding industrial and scientific environments where fastener security is paramount. Constructed from hardened alloy steel, each washer features a precision‑cut split design that creates a spring‑like tension when installed, locking the nut or bolt in place. The yellow‑chromate coating provides a corrosion‑resistant barrier while adding a distinctive visual cue for easy identification. With an outside diameter of 1.5 inches, a thickness of 0.35 inches, and a 3/4 inch fastener size, these washers fit a wide range of standard hardware. The package includes 20 washers, each weighing a negligible 0.01 ounces, making them lightweight yet robust. Their round shape and split head style conform to ANSI standards for spring lock washers, ensuring compatibility with most fastening systems. The product is sourced from The Hillman Group, a trusted name in hardware, and carries the Grade 8 rating, indicating superior strength and durability.

Usage

These split lock washers excel in applications where vibration, shock, or thermal cycling could cause traditional washers to loosen. Typical use cases include machinery assemblies, automotive components, electrical enclosures, and HVAC systems. Install the washer between the nut and the mating surface; the split creates a slight deformation that maintains constant pressure, preventing the nut from backing off. The alloy steel construction tolerates high torque values, making it suitable for heavy‑duty bolts and screws. The yellow‑chromate finish not only resists rust but also endures exposure to chemicals and outdoor elements, making these washers ideal for marine, agricultural, and construction settings. Whether you are building a prototype, maintaining equipment, or performing large‑scale production, the 20‑piece pack provides enough inventory to support repeat installations without frequent reordering.

FAQ

What size fasteners are compatible with this washer?

The washer is sized for a 3/4 inch fastener, which corresponds to a standard 1/2‑13 UNC bolt or screw. It fits any nut or bolt with a matching thread diameter, making it versatile for a broad range of hardware.

Can these washers be used in outdoor or marine applications?

Yes. The yellow‑chromate coating provides a protective barrier against moisture, salt, and chemicals, allowing the washers to perform reliably in outdoor, marine, and coastal environments where corrosion is a concern.

How does the split lock design differ from a plain washer?

A plain washer distributes load evenly but does not prevent rotation. The split lock washer has a cut that creates a spring‑like action, maintaining tension on the fastener and resisting loosening caused by vibration or thermal expansion.

What is the benefit of purchasing a 20‑piece pack?

Buying in bulk ensures you have sufficient inventory for multiple projects, reduces per‑unit cost, and minimizes the need for frequent reordering. This is especially valuable for maintenance teams and manufacturers who require consistent supply.

Is there a warranty or guarantee for these washers?

Hillman provides a limited warranty that covers material defects and coating failures under normal use. If you encounter any issues, contact our customer service team for a replacement or refund, subject to the warranty terms.
