1-1/4 x 1.875 OD Carbon Steel Wedge Lock Washers – 25 Pack

Description

Product Overview

The 1-1/4 x 1.875 OD carbon steel wedge lock washers are engineered to provide a secure, vibration‑resistant fastening solution for a broad spectrum of industrial applications. Constructed from high‑grade carbon steel and case‑hardened to a Rockwell hardness of 40‑55, each washer offers a durable, corrosion‑resistant surface that maintains torque integrity even under demanding conditions. The wedge design creates a self‑locking action that prevents loosening, making these washers ideal for machinery, automotive, and construction projects where reliability is paramount.

Measuring 0.265 inches in thickness, the washers fit a wide range of bolt sizes, ensuring compatibility with standard hardware. The finish, known as Delta Protect, adds an extra layer of protection against rust and wear, extending the service life of the fastener assembly. Packaged in a convenient 25‑piece box, the washers are ready for immediate deployment, reducing inventory handling time and simplifying procurement for maintenance teams.

Manufactured by DISC‑LOCK, a recognized leader in fastener technology, the product meets rigorous quality standards and is backed by a comprehensive warranty. The GD‑112 model number reflects the precise dimensions and material specifications, allowing engineers and purchasing agents to quickly verify suitability for their projects. With a best‑seller rank of #71 in the Wedge Lock Washers category, these washers have earned a reputation for performance and value.

Designed for general‑purpose use, the washers excel in applications ranging from heavy‑duty equipment to light‑weight assemblies. Their ability to absorb vibration and maintain clamping force reduces the risk of component fatigue, contributing to longer equipment lifespans and lower maintenance costs. The compact size and lightweight nature (approximately 3 pounds per box) make them easy to store and transport, supporting just‑in‑time inventory strategies.

Overall, the 1-1/4 x 1.875 OD carbon steel wedge lock washers combine material strength, precision engineering, and user‑friendly packaging to deliver a cost‑effective fastening solution that meets the exacting demands of modern industrial environments.

Usage

These washers are suited for a variety of settings, including manufacturing plants, automotive repair shops, and field service operations. Their self‑locking wedge design is particularly effective in environments with high vibration, such as engines, compressors, and heavy machinery, where traditional flat washers may fail.

Installation is straightforward: place the washer beneath the nut or bolt head, tighten to the recommended torque, and the wedge action will secure the assembly. The washers perform well with both steel and stainless‑steel fasteners, making them versatile for mixed‑material applications. For maintenance personnel, the 25‑piece packaging simplifies bulk ordering and ensures that the right quantity is on hand for routine service tasks.

When used in construction projects, the washers help maintain structural integrity by preventing bolt loosening caused by wind or seismic activity. Their corrosion‑resistant finish also makes them suitable for outdoor installations where exposure to moisture and chemicals is a concern.

FAQ

What bolt sizes are compatible with these washers?

The 0.265‑inch thickness and 1‑1/4 x 1.875 OD dimensions allow the washers to work with standard bolt diameters ranging from 1/4″ to 1/2″. For exact fit, consult the manufacturer’s sizing chart or test with a sample bolt.

Can these washers be used in outdoor or marine environments?

Yes. The Delta Protect finish provides a high level of corrosion resistance, making the washers suitable for outdoor installations, marine applications, and any setting where exposure to moisture or chemicals is expected.

How does the wedge lock mechanism prevent loosening?

The wedge design creates a spring‑like action when the nut is tightened, generating continuous pressure that resists rotational forces. This self‑locking effect maintains clamping force even when the assembly experiences vibration or thermal expansion.

What is the warranty coverage for these washers?

DISC‑LOCK offers a limited warranty that covers material defects and workmanship for a period of one year from the date of purchase. If a defect is identified, contact our support team for a replacement or refund.

Are there bulk purchasing options available?

Yes. For larger projects, we provide volume discounts and can supply the washers in custom pack sizes. Reach out to our sales department to discuss pricing and packaging options tailored to your needs.
