Hand screws (sometimes written thumbscrews) are multi-purpose fasteners designed to be tightened and loosened manually without the need for tools such as screwdrivers or wrenches for installation. They have a wide range of useful applications, especially in parts, materials and structures that do not easily support the use of hand or power tools. This is often due to space constraints.

Hand screws and thumb bolts may also be useful solutions in situations where you may need to remove components or panels on a regular basis. They can make tasks such as maintenance or cleaning quicker and easier than using mechanical screws, bolts or rivets that are fully tightened with a driver.

Knurled Hand Screws

Knurled hand screws are often chosen because they give the user a better grip during manual installation. These types of knurled bolts and screws are called knurled because of the knurling pattern found around the head of the screw - a series of ridges or bumps formed by machining. Knurling is a widespread manufacturing technique used to improve grip or torque forces between various components and fasteners that are manually installed.

Hand Screw Knobs

Hand screw knobs, often referred to simply as thumb knobs, are closely related to hand screws. However, they are specifically designed to be used as a quick, easy-to-remove fastening solution to tighten something and release it when needed.

Applications

Hand screws can be used in a variety of tasks and assemblies. Their primary use is to fasten panels, wiring, covers, safety covers, battery compartments, and any part or assembly that may need to be removed and reinstalled frequently.

Carbon Steel Properties

Carbon steel, also known as carbon steel, is an iron-carbon alloy with a carbon content of Wc less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, phosphorus.
