why two types of screws?

[shadow]

I have been meaning to ask this for a long time, I know I can look for the answer over the net, but baka meron may alam sa inyo.

bakit kailangan two types pa ang mga screws I mean yun cross and flat?

[nels76]

Hindi lang Philips (Cross) and Flat.
Meron pang Torx (6 ang slots) as compared to Philips' 4.

onga no. tapos meron pa pang allen wrench.

different standards? different countries? different torque requirements? :s

i guess shadow didnt see that coming

[bmacavanza]

Different designs or types for various product and industry appicationsl. like sa electronics dito sa laptop ko, puro cross. para secured ang screw driver or tool while tightening or the other way around.

Another thing like allen heads. To ensure only professionals can do the job. Like sa cars. the same sa mga special tools.
