## Description

Hex Bolts Advantages of hexagonal screws With their hexagonal shape, hex bolts allow higher torque than conventional round head screws. You cannot install or remove them with a standard screwdriver bit such as a flat head or a Philips head. Instead, you need to use a combination of ratchet and socket wrench. Also known simply as a socket wrench, allows you to insert the socket over the head of the hex bolt. After positioning, you can turn the socket wrench to install or remove the hex screw. The socket wrench grips all six sides of the head, so you can generate more torque. Hex bolts also peel off less easily than their conventional counterparts. The head of a conventional screw may come off when installing or removing. If the bit is inserted into the drive recess of the head, the screw may be damaged during installation or removal. Hex bolts distribute this torque across all six sides, making stripping less likely. Specifications: Head Type: Hex Material: galvanised steel. Size: M8 x 40.
