BS EN 3782 is a European standard on aerospace series which covers holes for 100° countersunk head screws and a design standard.
BS EN 3782 specifies holes in common parts and sheet metal for 100° countersunk head screws with nominal diameters of 3 mm to 5 mm and head configuration according to EN standards for aerospace applications.
BS EN 3782 on holes for countersunk screws is useful for:
Countersunk screws sink into objects and surfaces. They feature a flat head that tapers along the shaft. Therefore, when you drive a countersunk screw into an object or surface, the head will sink so that it's flush with the respective material.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 3782 specifies holes in common parts and sheet metal for 100° countersunk head screws with nominal diameters of 3 mm to 5 mm and head configuration. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
