Hammer drive screws consist of a round head and a shaft with coarse helical knurling
Simply driven into a pre-sized hole by hammer or with a press
The knurls grip the inside of the hole and resist rotational loosening
Used as a permanent, tamper resistant fixing where the need to remove the pin is unlikely
Simple, low-cost assembly, often used to attach plate materials to unhardened metals
Unlike machine screws, do not depend on a tightening torque to be retained in the assembly
Resistant to back-out, without the need for lock washers
Steel pins with an aesthetically appealing electro brass finish
