Ball Knob SBDs Black ABS Plastic Female 3/8″-16 Thread 1-3/8″ Dia

Description

Product Overview

The SBDs Black Phenolic ABS Plastic Ball Knob Female is engineered for demanding industrial applications where durability and precision matter. Constructed from high‑impact Acrylonitrile Butadiene Styrene (ABS) plastic, the knob offers a smooth, polished finish that resists scratches, chemicals, and UV exposure. Integrated within the plastic body is a brass‑coated metal insert that provides a robust 3/8‑16 thread, ensuring a secure fit in a variety of mounting holes. With a depth of 15/16″ and a diameter of 1‑3/8″, the knob delivers a substantial projection of 1.5 inches, giving users a comfortable grip while maintaining a compact profile. The overall weight of just 1.02 ounces (28.92 grams) makes it lightweight yet capable of handling heavy‑duty loads, making it an excellent choice for both static and dynamic environments.

Designed for ambidextrous use, the knob can be installed on either side of a panel without concern for orientation, simplifying inventory management and reducing installation time. The polished brass exterior not only adds an aesthetic appeal but also enhances corrosion resistance, extending the product’s service life even in humid or corrosive settings. The threaded attachment mechanism allows for quick, tool‑free installation, and the standard locking shaft ensures the knob remains firmly in place under vibration or repeated use. This combination of material science, thoughtful engineering, and user‑centric design makes the SBDs ball knob a reliable component for a wide range of industrial hardware assemblies.

Usage

In window hardware, the ball knob provides a sleek, low‑profile control that blends seamlessly with modern architectural designs. Its 3/8‑16 thread matches common window latch mechanisms, allowing for straightforward retrofitting of existing frames or new installations. The knob’s ergonomic shape ensures that users can open and close windows with minimal effort, reducing strain during frequent operation in commercial or residential settings.

Beyond windows, the knob excels in machine tools, jigs, and fixtures where precise positioning and secure locking are essential. The brass‑coated insert tolerates repeated tightening and loosening without stripping, making it ideal for applications such as CNC machine adjustments, workbench accessories, and test equipment where adjustments are routine. Its heavy‑duty construction also supports fitness equipment weight stacks, providing a reliable pin or key that can handle the dynamic loads generated during strength training sessions.

For industrial environments that demand reliability under harsh conditions, the ABS plastic body resists impact, chemicals, and temperature fluctuations, while the polished brass finish protects against corrosion. Whether installed in a manufacturing line, a laboratory, or a gym, the knob’s versatile design and robust performance ensure consistent operation over the product’s lifespan.
