Set of 4 Stainless Steel Fuel Rail Mounting Bolts for TBSS/NNBS/NBS Truck Intakes. These are the correct size for mounting OEM and aftermarket fuel rails to the 99-13 GM Truck and TBSS intake manifolds. These are internal hex (allen) socket head fasteners which allow for greater rail and bracket clearance compared to standard hex head fasteners and they are long enough to be used with up to 5mm fuel rail height spacers.
