Q1. What does the ASTM A992 grade primarily specify?
A) Weathering steel for bridges
B) Wide-flange shapes for building framing
C) Hollow structural sections
D) Bolt shear strength
Answer: B
Rationale: A992 is the standard specification for structural
shapes (W, S, M) used in building framing. It has a 50 ksi
minimum yield strength and improved weldability.

upon request. Sample continues below.)
SECTION 2 – BOLTING & CONNECTIONS (Q31–60)
Q31. A325SC bolts are tightened to which condition?
A) Snug-tight only
B) Slip-critical (SC) – pretensioned
C) Finger-tight
D) Turn-of-nut beyond snug with no verification
Answer: B
Rationale: SC = Slip-Critical. These require pretensioning and
surface preparation to prevent slip at service loads.
Scenario Q45. You inspect a moment connection where 1⅛”
A490 bolts are installed. The contractor used a calibrated torque
wrench and achieved 450 ft-lb. The RCSC spec requires 480 ft-

lb ±10%. Is this acceptable?
A) Yes, 450 is within ±10% of 480
B) No, below minimum required torque
C) Only if 10% of bolts are retested
D) Yes, if turn-of-nut was also used
Answer: B
Rationale: 480 × 0.9 = 432 ft-lb minimum; 450 > 432
technically passes, but careful: 450 is below 480. The range is
432–528, so 450 is acceptable. Wait – correction: the question
says “required 480 ft-lb” – RCSC allows ±10% of specified
installation torque, so 450 is within 432-528. Correct answer is
A. Trick scenario tests attention to tolerance.
SECTION 3 – WELDING INSPECTION (Q61–90)
Q61. According to AWS D1.1:2020, a “CJP” groove weld
requires what NDE method for complete inspection?
