Knurled thumb screws are hand-tightened fasteners designed for applications that require frequent adjustments. They are commonly used in electronic hardware and feature a textured (knurled) head that allows users to securely tighten and loosen components by hand.
At RC Fasteners, we distribute knurled thumb screws in plain or washer face styles. Our inventory includes aluminum and stainless steel options, a full range of sizes, and volume discounts on bulk orders for manufacturing and industrial applications.

Why Knurled Thumb Screws Are Used in Electronic Hardware
Electronic assemblies often require periodic access, whether for maintenance, inspection, upgrades, or component replacement. Traditional fasteners can slow this process and introduce the risk of over-tightening. Knurled thumb screws solve those problems. With a head pattern that increases friction between the user’s fingers and the fastener, they can be tightened securely without tools. Advantages include:- Faster installation and removal
- Reduced risk of damage caused by too much torque
- Convenient access to internal components
