TIME-SERT 6250 Universal Head Bolt Thread Repair Kit M10x1.25mm

Includes Free Shipping. The TIME-SERT 6250 head bolt thread repair kit is a universal head bolt thread kit that can be used on a variety of automobile engines that use the 11 millimeter by 1.5 millimeter bolt size. This is for a "first time" repair which means it has never had a repair insert of any kind installed previously. For second time repairs use a Big Sert kit which has the letters BS following the numeric kt number (6250BS). We have a partial application list below.

The 6250 is considered a "universal" kit because the tooling has an adjustable stop that can be adjusted to work on holes of different depths. Although, it works on other cars is is mostly used Honda engines. We recommend installing all the inserts while the head is off to help eliminate the possibilty threads pulling when installing the head bolts and torquing to the maufacturer's specifications (torque specs). That also eliminates weak links that the remaining aluminum threads would end up being, that could possibly fail shortly after the car is back on the road. Therefore it's recommended to upgrade to the much stronger tensil strength steel, bushing type inserts (part number 10129) that are included in the Time-Sert 6250 head bolt thread repair kit. TIME-SERT is recommended by leading automobile manufacturers.
