Review: I bought these to sink in deck joists that started to separate. They drove easily with the impact driver and I could just watch the joists sink in. the included drill bit is a nice to have so you don't have to remember to bring/buy the right star bit. Review: You can see from the pics, it is lighter than the comparable S.p.a.x. lags. It is not as wide, and the head is much smaller. So: not as strong, doesnt grab as much wood, but other than that no complaints. Do not use it for structural purposes anyone who knows construction will not be impressed. ## Features - 【DIMENSIONS & SUPERIOR STRENGTH】Thread Diameter 0.171" - Head Diameter 0.55" - Length 3" - Use with T30 Star Bit.
