General Q & A / security bit fasteners
May 08, 2018, 02:39:53 PM
Can't unbolt my fresh water pump from floor cause of security type fasteners.  Appear to be the 8 sided type but with a dimple in the middle so I can't use a  tapered 4 sided bit on them.   Best I can tell t-25 is the size I need so I went to amazon and bought a whole range of them including this size in 4 and 8 sided with the hole in the middle to accommodate the dimple on the fastener.

None of them fit.  Any suggestions how I can get these fasteners out?  Can't reach them with a pair of pliers.  Considering drilling out the center of them and using an easy out.
