M3 x 18mm Hexagonal Allen Head Stainless Steel Bolt

Hex socket screws, also known as Allen screws, are bolts with a hexagonal depression at their heads, typically tightened or loosened using an Allen wrench. These hex socket screws have these hexagonal sockets to allow the wrench to snugly fit and turn at the head of the bolt.

Available in metric or imperial measurements, hex socket screws are widely used in various applications. They can be found in electronics, automotive industries, furniture assembly, construction projects, and many other fields.

The advantages of hex socket screws include their low profile, ability to provide high clamping force, ease of use in tight spaces, and generally less tendency to strip compared to other fasteners. These features make hex socket screws preferred in many applications.

One disadvantage of hex socket screws is that they require a special Allen wrench instead of a standard wrench. However, many hex socket screws can be tightened or loosened with a regular wrench.

In conclusion, hex socket screws are reliable and effective fasteners used in a wide range of applications.
