Our Socket Head Screw Caps are available in a variety of forms and materials, serving different uses. Most commonly is to use for the inside UPS boxes when high voltage cables pass close to metal screw heads, which occurs when space is limited. The cap can be applied in order to prevent interference between the two, as the screw head needs to be isolated. These caps can also protect against dust and dirt. Our range is offered in Grey, White or Black and made from Silicone or Low-Density Polyethylene.
