Lawrence & Scott 3/4 inch Brass Lock Washers 5pcs for 1/4 IPS Lamp

Description

Product Overview

The Lawrence & Scott 3/4 inch brass lock washers are precision‑engineered components that feature an internal tooth design. This tooth creates a mechanical lock between the washer and the bolt head, maintaining tension and preventing loosening caused by vibration. Constructed from solid brass, the washers deliver excellent corrosion resistance and a smooth plain finish that integrates seamlessly into any lamp assembly or industrial application.

Each washer measures 0.78 x 0.78 x 0.04 inches and weighs only 0.2 ounces, making them lightweight yet robust. The pack includes five identical washers, providing a ready supply for multiple projects or for keeping spares on hand. Their 3/4 inch size is specifically matched to 1/4 IPS lamp pipe threads, ensuring a perfect fit without the need for additional adapters or modifications.

These lock washers are ideal for both professional technicians and hobbyist makers who require reliable fastening solutions for lamp repair, custom lighting builds, and other small‑scale mechanical assemblies. The internal tooth design works in conjunction with standard hex bolts, delivering a secure, vibration‑resistant joint that extends the life of the equipment.

Usage

When installing or repairing a 1/4 IPS lamp, place the brass lock washer between the bolt head and the lamp pipe. Tighten the bolt to the recommended torque, and the internal tooth will bite into the pipe material, locking the assembly in place. This method is especially effective in environments where the lamp may be subject to frequent movement, such as stage lighting, studio setups, or portable work lights.

The washers also perform well in other applications that demand a secure, non‑slipping connection, including small machinery, electronic enclosures, and prototype fixtures. Their brass composition makes them suitable for use in humid or mildly corrosive environments, providing long‑term stability without the need for frequent replacement.

FAQ

What size bolt should I use with these lock washers?

The washers are designed for standard hex bolts that fit a 1/4 IPS lamp pipe. Typically, a 1/4‑20 bolt works well, but any bolt with a compatible head diameter will engage the internal tooth effectively.

Can these washers be used in outdoor lighting applications?

Yes. The solid brass material resists corrosion, making the washers suitable for outdoor fixtures, provided the environment is not highly acidic or exposed to extreme salt spray.

Do the washers require any special installation tools?

No special tools are needed. A standard wrench or socket set is sufficient to tighten the bolt to the recommended torque, allowing the internal tooth to engage automatically.

Are the washers reusable after removal?

Because the internal tooth is designed to bite into the mating surface, the washer can be reused if the tooth has not been deformed. For best results, inspect the washer after removal and replace if any damage is visible.

What is the difference between these and plain lock washers?

Plain lock washers rely on a split‑ring design to create friction, whereas the internal tooth washers provide a mechanical lock that offers superior resistance to vibration‑induced loosening, especially in small‑diameter applications like lamp pipes.
