If the screw starts to turn and then binds, apply rust penetrant to the screw head and turn the screw in and out several times to spread the penetrant down the threads. Repeat if necessary. Free of most of its rust and well lubricated, the screw should come out easily.
Come the nineties and the post-martial law governments reoriented the economy to a more outward looking slant. Also, like Pakistani banking, Pakistani consumers changed too. The opening of the economy, along with the rise of satellite TV, the Gulf boom, mobile telephony and the arrival of the internet, significantly changed consumer preferences. Despite the ‘on again, off again’ recessive tendencies of the economy, increased competition among banks forced them to look beyond corporate and high net worth customers. This broadening of the target audience brought consumer banking in its true form to the Pakistani market.
The Robertson screw offers the distinct advantage of reduced screwdriver slippage. Also known as the “square recess screw,” this screw head was developed in the early 1900s by a Canadian inventor who was tired of damaging slotted screws every time the screwdriver tip slipped out of the slot. Though a great improvement, it didn’t catch on in the US until power drills began being used as screwdrivers. Today, the Robertson screw, which ranges in recess size from 1/16” to 3/16”, is extensively used in construction and remodeling projects. You can find manual and ratcheting square recess screwdrivers, but the Robertson screw is most often inserted and removed using a power drill. One of the most common uses for the Robertson screw is in the installation of subflooring, which goes a lot quicker if you use a power drill and a Robertson screw bit.

Flat head screwdrivers can be further categorised, ones where the sides of the blade are parallel and within the profile of the shaft and ones where the blade is inexplicably flared to be wider where it meets the shaft the only purpose of which is to stop you from using it down small holes. Stanley sell and market sets with both types so there is apparently a difference.
