Описание: Philips cross-point screwdrivers and crosshead screws were designed during World War 2 for mass production when all the countries were building aluminum aircraft. Aircraft manufacturers needed a self centering screwdriver and screw combination to speed up production. Because the crosshead steel screws were used to screw aluminum plate together, the design had to be such that the steel screws did not strip in the aluminum plate due to over-tightening! Thus the Philips design was made so that it will cam-out when the screw was in tight enough at about 2Nm. This worked well for the application and manufacturers started using The Philips Cross-point/crosshead design for all types of manufacturing. In 1969 the Japanese re-designed the cross-point screwdrivers and crosshead screws so that they won't cam-out. This was called the Japanese Industrial Standard (JIS) and has been in use ever since on all Japanese products, even if they are made in another country. This Video shows the difference between the Philips and JIS designs and also the correct use of VESSEL Japanese Industrial Standard (JIS) Screwdrivers.
