generally known as the Robertson push, its unique layout is characterised by a square-shaped socket while in the screw head in addition to a square protrusion about the Instrument. The Instrument plus the socket are each marginally tapered.
Certainly, screw dimension charts can also be utilized for bolts since they follow identical sizing specifications. even so, it can be crucial to check for any special needs for the particular software.
The slotted screw travel is effective finest when hand-driven; it can be Generally not applied with electrical power equipment due to Risk on the screwdriver slipping out on the slot and harmful the surrounding material. it can be most suitable for easy carpentry, where by the torque applied is fewer. Phillips Head Drive
