## Description

Thread Diameter: 3mm (M3).The flat/countersunk head socket screws are bolts designed to fit inside a countersunk hole. A countersink is both the recessed hole and the tool to make the hole that allows compatible screws and bolts to screw in flush to a surface. Flat/Countersunk head screwss are mostly hidden when screwed in, because their heads are shaped to fit within the special holes. When these holes are empty, they look like a normal screw hole with a conical opening at the top; when they are full, the only visible part should be the very top of the screw or bolt.The typical angle of a countersunk screw head is 90 degrees. Screws Length= Head Height + Thread Length, e.g. M3 x 8mm flat head socket screw, the screws length is 8mm, head height is 1.7mm, thread length is 6.3mm.

These were exactly what I was looking for. Excellent quality screws. Perfectly cut with no burs at the tip where the threads begin. They screwed in nicely. I only needed 4 screws but for the price and quality, I now have 96 spares. Only CON: It took 2 FULL weeks for delivery
