Because it is made from a different steel with a thinner wall and can shatter under impact. An impact socket is built for the hammer blows a gun delivers, and the difference is structural rather than cosmetic.
The one matching the gun. Drives run 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch and 1 inch across the range, and the socket size is then chosen against the fastener.
A hexagon profile bears on the flats and grips a good fastener more strongly. A bi-hexagon has twelve points and engages at half the angle, which helps where there is little room to swing the tool.
A standard socket is shorter and stiffer. A deep socket reaches over a protruding stud or a long thread, which is the only way to reach some nuts. Both lengths are held across the drive sizes.
Splined fastener heads that no hexagon socket will engage. They run T20, T45, T50, T55, T60 and T70 on 1/2 inch square drive, so they fit a standard impact gun.
Drive size, socket size and profile per socket, which is what allows a set to be filled without duplication or a gap being left in the size ladder.

An impact socket is made from a different steel and a thicker wall than a chrome socket. That is what lets it take the hammer blows an impact wrench delivers without shattering, and it is why a chrome socket must never be used on an impact gun however well it fits. The colour finish is the visible difference but it is the wall thickness and the steel that matter.
Drive size matches the gun and socket size matches the fastener, and both are stated on every listing. The drives here run 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch and 1 inch, with the 3/4 inch Draper HI-TORQ ladder covering 17mm, 18mm, 20mm, 23mm and 25mm among the wider size range.
Profile decides how the socket grips. A hexagon profile bears on the flats and is the stronger grip on a fastener in good condition. A bi-hexagon profile has twelve points, which engages at half the angle and suits a socket that has to go on where swing is limited. Bi-hexagon is also more forgiving on a fastener whose corners have already been rounded.
Length is the other variable. A standard socket is shorter and stiffer; a deep socket reaches over a protruding stud or a long thread. TX-STAR impact bits at T20, T45, T50, T55, T60 and T70 on 1/2 inch drive cover splined heads that no hexagon socket engages. Questions go over WhatsApp on 07754288583. The Sealey and PCL impact estates run alongside Draper across all five drive sizes.
