The two newcomers to the PGA Tour have dominated the opening two rounds of the first full-field event of the season and for the third straight day will be paired together when they tee off in the final group on Saturday.
Hensley did not make a bogey at the Waialae Country Club Friday and posted a 36-hole total of 14-under 126.
Langley, who led the event with a 62 Thursday in his first round as a tour member, added a 66 Friday and his 128 total left him in a second-place tie with Scott Piercy.
Hensley reached the tour this year by finishing among the leading money winners on the Web.com Tour last season. Langley earned his rookie status with a 17th place finish in the qualifying tournament.
Matt Kuchar was alone in fourth at 129 following a 63. He rolled in a 16-foot eagle putt at the final hole to reach that total.
Dustin Johnson, who began the golf season with a victory last week at the weather-marred Tournament of Champions on the island of Maui, withdrew midway through the second round with flu-like symptoms.
Johnson shot a 70 on Thursday and was 3-over for the day Friday when he withdrew.
Among those making the cut was John Daly, who finished at 138 following a 68.
