BOLT DIAMETER

f =0.875in ( 7/8 in)BOLT MATERIAL (A307, A325, A490)ASTM =A325HOLE TYPE (STD, SSLT, SSLP, OVS, LSLP, LSLT)

LSLT

STD =Standard Hole

SSLT =Short-Slotted Hole oriented transverse to the line of force SSLP =Short-Slotted Hole oriented parallel to the line of force OVS =Oversize Hole

LSLP =Long-Slotted Hole oriented parallel to the line of force LSLT =

Long-Slotted Hole oriented transverse to the line of force

LOADING (S=single shear,D=double shear)D

CONNECTION TYPE (SC-1, SC-2, N, X, "-")

SC-1

SC-1 =Slip-Critical Connection, slip is a serviceability limit-state SC-2 =

Slip-Critical Connection, slip is a strength limit-state

N =Bearing-Type Connection with threads included in the shear plane X =

Bearing-type connection with threads excluded from the shear plane
