Skipper Chris Morgan rescued the Blades to extend the draw sequence to six matches in all competitions.
The powerful defender fired in from the edge of the penalty area with 12 minutes to go to earn United a point in a difficult trip to Queens Park Rangers.
Colombian teenager Angelo Balanta opened the scoring for Rangers in the first half before Morgan struck to extend United's unbeaten run to seven matches in Kevin Blackwell's first Championship encounter in charge of the Blades.
Boss Blackwell's only change to the starting line-up was enforced because of injury. Sharp and Geary recovered from their problems but Martin's hip complaint forced him to miss the trip to the capital and his place was taken by Armstrong. The hosts included former Blade, Leigertwood, and in-form striker, Agyemang, who netted at Bramall Lane in the earlier league fixture between the teams.
United made a bright start with everyone looking get forward at every opportunity. At times in the early stages QPR struggled to clear cleanly, whilst the rhythm was interrupted by the fact that the ball flew over the main stand, twice! Camp and Morgan were the guilty parties.
On three minutes, following a quick release by Kenny, Tonge fired well over from 25 yards , although he was hampered by a bobble just as he was about to shoot. Rangers won the first corner of the match soon after when Stead was robbed of possession and Leigertwood should have done better with his header after a drilled delivery from Delaney.
United's first corner arrived on 11 minutes when Hall flicked Armstrong's cross away from Sharp but QPR began to enjoy a spell of possession, which included Vine firing over after a break down the right.
The Blades, however, were not so fortunate on 19 minutes, conceding a goal for the first time in four matches following a Rangers break. On the right, Ephraim worked himself a yard to get away from Naysmith and his cross just needed deflecting in by BALANTA, who had made his away in from the left flank.
Rowlands was orchestrating play for the home side after being given too much space to move the ball and he was well supported by Leigertwood. United, though, caused problems in the home defence on 25 minutes following a Tonge corner. Morgan and Beattie both challenged for aerial balls, whilst Rangers cleared as Kilgallon and Stead closed in.
Later in the half the Blades were unable to recreate the form of the first ten minutes. Before the interval, Sharp was crowded out when trying to latch on to a Beattie flick on, whilst, in injury-time, Stead was forced to block a shot from Rowlands.
Both managers resisted the urge to make a change at the interval and in a lively opening, there were half-chances at both ends. On 50 minutes Vine's long-range shot was wide and then Balanta forced a save out of Kenny. For United, with 52 minutes gone, Stead got the better of Delaney and delivered from the right which Armstrong and Beattie challenged for, with the latter deflecting the ball wide. Within 60 seconds, Tonge drilled well wide of Camp's goal.
On 55 minutes Armstrong volleyed across the box but Connolly cleared at the expense of a corner with Beattie poised, whilst Tonge looked to be United's biggest threat and the midfielder won a corner from Rowlands around the hour mark.
The Blades were enjoying more possession than the home side, whilst the more direct style adopted by the visitors made the action frantic and disjointed. Blackwell made a change with Cotterill being introduced for Sharp, which meant a switch to a central role for Stead.
Following a fine ball by Rowlands, Kilgallon was forced to block from Vine, whilst at the other end Hall prevented Stead making progress.
Blackwell threw caution to the wind, using the remainder of his substitutes by replacing the front two and the change served to unsettle QPR. The Blades levelled within a minute of the replacements entering the field following Kenny's long clearance.
MORGAN challenged for the initial header and after the home side could only half clear, the captain swivelled and fired through a glut of bodies, with Camp unable to prevent the ball sliding into the net close to his right post. The subsequent celebration involved all ten outfield players.
Morgan's central defensive partner, Kilgallon, needed to be alert to make a valuable interception from Agyemang, but late on it was United who forced the issue and looked the more likely to claim a second.
With Quinn and Armstrong particularly prominent, Camp and his defenders were put under severe pressure. The Blades won two corners in the three minutes of injury-time but a winning goal, which Blackwell so craved, failed to materialise.
