Hex Screws - Overview

Hex screws, also known as hex head screws or hex bolts, are threaded fasteners with a hexagonal (6-sided) head designed to be tightened or loosened with a wrench or socket. They are commonly used in various applications like construction, machinery, and automotive due to their strength and ability to handle higher torque than other screw types.

Types of Hex Screws

Internal hex screws

Internal hex screws have an internal-facing head indentation and are a common choice for furniture pieces. They require an Allen wrench for installation and removal.

Combi screw

Combination screws, also called combi screws, refer to any screw type that combines more than one head style. Common combi hex screws are slotted hex fasteners or hex and Phillips head combinations for easy use with a standard screwdriver.

Lag screws

Lag screws are heavy-duty fasteners for landscaping, lumber and thick sheet metal applications. They are large with coarse threads and support more weight than standard hex screws. Lag screws with hex heads are often used for wood and sheet metal materials requiring high torque levels.

Sheet Metal Screws

Some hex head screws have built-in washers where the head meets the shank. They have a sharp point on the end for effectively penetrating wood and sheet metal. This design distributes weight evenly over the screw's entire area for metal-to-metal fastening and some heavy-duty loads.

Zip screws

Many hex washer head screws are also self-piercing. These are usually referred to as zip screws.

Application

Machinery

Hex head screws are a common choice for fastening and disassembly in machinery projects and equipment assembly.

Construction

Hex screws are used in masonry and construction projects, especially those using steel and wood.

Tight spaces

With six access points, hex head screws are easier to access in tight spaces or spaces with only one side clearance for installation, tightening or removal.

Dirty applications

Hex screws with a solid head instead of an indented or recessed one are perfect for dirty applications, where debris and build-up might threaten the screw's integrity over time. With no opening to fill, there's no chance for clogging, and they're easy to wipe down and shine if appearance or hygiene is important.
