What are Plastic Knurled Thumb Screws?

Plastic Knurled Thumb Screws are precision-engineered components designed to facilitate frequent manual adjustments in various applications. These specialised fasteners boast a unique design feature - a knurled, thumb-shaped head that offers a firm grip, allowing for secure tightening and loosening by hand. Being fabricated from high-quality nylon plastic, these screws exhibit inherent corrosion resistance and electrical insulation, making them the choice for applications where metallic fasteners are unsuitable.

How Plastic Knurled Thumb Screws Work.

In action, Plastic Knurled Thumb Screws operate by threading into a pre-tapped hole or a threaded insert. Unlike traditional screws, these are primarily designed for manual operation. Their knurled exterior on the screw head offers a textured, grip-friendly surface, which enables the operator to easily adjust, tighten, or remove them by hand without the need for tools. This distinguishing feature makes Plastic Knurled Thumb Screws especially beneficial in precision-engineered applications requiring frequent component adjustments or tool-less assembly.

The slotted head of our Plastic Knurled Thumb Screws does allow for the use of a flat-head screwdriver when applying torque, however, caution must be taken so as to not over-tighten and risk stripping the head.

What Material Are Plastic Knurled Thumb Screws Made From?.

Crafted from high-performance thermoplastic polymers such as polyamide (nylon), our Plastic Knurled Thumb Screws are not just lightweight but also robust. These thermoplastics offer a unique blend of properties - excellent durability, corrosion resistance, and electrical insulation, ensuring that these screws deliver optimal performance even in the most challenging environmental conditions.

What Size and Type Plastic Knurled Thumb Screws Are Available?.

At Accu, we offer a comprehensive range of Plastic Knurled Thumb Screws in a variety of sizes ranging from M4 (4mm) to M6 (6mm) and lengths from 6mm to 20mm.  If you'd prefer a white finish to your plastic thumb screws, Accu also stocks a range of Reduced Diameter Plastic Thumb Screws which also have a more slimline appearance and would be ideal for scenarios where less torque is needed to fasten these screws.
