Application Technology

Sealing socket head cap screws for tight space applications are used across a range of sectors including electronics, automotive and industrial machinery sectors, particularly where strength, economics and reliability are key considerations.

Available from APM Hexseal, the screws feature a barrel shaped head with a recessed hexagonal drive, with the head being dimensionally smaller than most other standard screws, making them ideal for confined areas of installation. They have also been designed for use in tight spaces and applications where aesthetics might be important, with a sleek design offering a clean appearance, with no protrusions.

The socket head cap screws can also achieve the same, or greater, clamping force as a standard screw and are suited to applications in other areas, such as in the manufacture of excavation equipment, in the energy generation sector, as well as in machining, tool and die, and furniture manufacturing sectors.

Other key advantages of using socket head screws, to those already mentioned, include fewer screws being required for the application, which results in lower component costs. This, in turn, also means fewer holes need to be drilled and tapped, leading to lower manufacturing costs. There will also be an expected end product overall weight reduction, due to the lower component count.

The screw’s socket head features a customised groove under the head, with an O-ring inserted. This creates a reliable seal and protects even the most sensitive systems and components. The product is available with a variety of O-ring materials and is said to provide the same high performing seal as other APM Hexseal products.
