M4 x 8mm Slotted Flat Point Grub Screws (DIN 551) - Brass Metric Slotted Flat Point Grub Screws, also known as Set Screws, feature a slotted drive, and a fully threaded shaft. Grub Screws are used to connect two objects together by threading into one and applying tension to the other. The high level of torque this produces results in a strong yet inconspicuous fastening. The Flat Point on this Grub Screw is less likely to cause damage to the material they are set into as, unlike the cup or cone point grub screws, they arent designed to dig into the surface of the fastened area but instead lay flush against it. Brass offers both high tensile strength and high corrosion resistance. Due to this, unless the item is deemed faulty, this item is non-returnable and non-refundable.
