This is a stronger upgrade set of screws for the front grip barrel/bushing found on 2011 pistols that use the classic design of a separate bushing (threaded cylinder) through the frame and that has threaded screws locking into it from both sides to keep the grip in place.
This set can replace the original screws with T10 torx heads that are less likely to strip out. It can be used as a replacement for OEM but is specifically designed for use to install the Inception Defense Flatline Thumbrest on 2011's that use UNC threads (STI, Staccato, Springfield, Kimber, Atlas etc.)
It comes with black and silver screws in each length that may be needed depending on your gun and grip design. If you want two screws the same length you will need to buy two sets or shorten one of the longer screws.
The mounting screws use a #10 Torx bit (available separately) for install.
We have a metric set of screws available to fit Bul Armory guns available here.
