Parallel Tip Screwdrivers?

[chris u'5]

I was out with my HW95K yesterday and noticed that the action has become quite loose in the stock.

Obviously it should hopefully just be a case on tightening the stock screws but I was just reading an article on the Air Arms website that said you should always use a parallel tip screwdriver on stock screws to avoid damaging the screw.

Now to be honest I am an expert at messing up the simplest of jobs of jobs and have damaged screws before by using the incorrect size of screwdriver but I've never heard of these parallel tip screwdrivers so I was just wondering if you could tell me what the difference between these and a normal screwdriver and will it prevent me damaging the screws?

I really does bug me when I cause paint damage or burrs on screw heads so any advice of this would be really gratefully received.

I know it's a stupid question but I am a pretty stupid guy so go easy

Thanks as always guys.

Not 100% but my understanding is that instead of having a constant tapering angle on the blade of the screwdriver from the shank to the tip, there is an area lading to the tip where both faces of the blade are exactly parallel. I guess this would improve the security of location in the screw head and reduce slippage and consequently burring of screw heads etc.

I asked a similar question the other day on this thread:

A lot of screwdriver sets with interchangeable tips have parallel sided flat tips and usually a good enough selection of sizes to ensure there is no excuse for selecting something very close to the ideal size.

What it's referring to is hollow ground screwdriver blades.. as mentioned above there's no wedge to chew up the screw heads. They are very good for old shotguns with handmade screws.

Ah, beautiful. They aren't cheap which makes them even more desirable!

A parallel tip is straight down each side from the shank. My guess that you need that is because they are cheese head screws and a flare tip screwdriver will foul on the wooden stock if the screw is recessed.

FYI a flare tip screwdriver is wider at the shank and they are good for countersink screws as the cut in the screw head will be slightly narrower at the bottom of the cut as it is at the top.

I used to be a branch manger of a tool shop and enjoy reading tons of absolutely pointless information in the hope that one day it may be useful........ I have finally been able to share some!
