To put it differently, 3 Robertson squares are superimposed at a successive thirty° rotation. The design is comparable to that of the double-sq., in each scenarios the idea staying that it resembles a sq. (Robertson) but can be engaged at a lot more Regular angles by the motive force little bit. These screws could be pushed with typical Robertson bits.

The neatest thing about bugle screw head types is that they’re self-drilling, which negates the need for just about any pilot-gap drilling before employing these.
Pin screw heads are the ultimate in safety since the defining aspect can perform with any from the screw head styles. the primary difference is there's a pin in the middle that stops the bit from remaining seated in the screw head.
