## Description

Hex Cap ScrewsBenefits of Hex Cap ScrewsWith their hexagonal shape, hex cap screws allow for greater torque than that of traditional screws with a circular head. You can’t install or remove them using a standard screwdriver bit like a flat head or Philip’s head. Rather, you’ll have to use a ratchet and socket combination. Also known simply as a socket wrench, it allows you to fit the socket bit over the head of the hex cap screw. Once positioned, you can turn the socket wrench to install or remove the hex cap screw. The socket wrench will grip all six sides of the head so that you create more torque.Hex cap screws are also less likely to strip than their traditional counterparts. The head of a traditional screw may strip when you install or remove it. When the bit is placed inside the head’s drive recess, it may damage the screw during installation or removal. Hex cap screws distribute this turning force across all six sides so that stripping is less likely to occur.Specifications:Head Type: HexagonalMaterial: Zinc plated SteelSize: M8x40
