TRUSCO Hex Lobe Ultra Low Head Screw Black Nickel M4 x 8 40 Pieces B181-0408 1 PK

Catalog number: B181-0408 Features: ●The head is very thin and lightweight. ●Hex lobe holes have excellent torque transmission because the driver and screw hole come into contact with each other on the surface, so the torque is applied to the center. This prevents cam-out (the driver coming off the screw) during work and improves workability. ●It can eliminate protrusions on thin plates that cannot be countersunk or countersunk. Applications: ●For equipment that needs to be lightweight, robots, drones, bicycles, motorcycles, etc. ●For places where countersinking and countersinking are not possible ●When you want to make something even 1g lighter ●When working, use a hex lobe driver (Torx driver) that matches the size of each driver.
