Why can’t I specify ‘flat end’ or ‘dog point’ for bigHead fasteners?
15 May 2026
Standard as-rolled (RL) and chamfered (CH) end-forms can feature a slightly recessed or dimpled stud-end.
Flat point (FL) and dog point (SD/LD) can look similar to the above – but they are not suitable for bigHead studs that receive a nut.
Flat point (FL) is intended for screws that bear against a surface. Dog points (SD/LD) are intended for screws that locate into holes or slots. Neither supports reliable nut engagement on a stud.
