I． Sucker Rod Pin Connections
I.1 Go Pin-thread Truncated Setting Plug Gauge, P7—This gauge represents the maximum permissible pitch diameter of the pin thread. It is used
1) in setting the mating ring gauge P8 and the corresponding working ring gauge.
2) in checking the shoulder squareness of the working gauge, and 3) for detecting wear
I.2 Go Pin-thread Ring Gauges, P8—This gauge mates with the P7 go pin-thread plug gauge. In case of dispute,this gauge may be used in gauging the product pin threads, but such use should be held to a minimum.
I.3 No-go Pin-thread truncated Setting Plug Gauge, P5*—This gauge represents the minimum permissible pitch diameter of the pin thread. It is used 1) in setting the mating ring gauge P6 and the corresponding working ring gauge and 2) for detecting wear；
I.4 No-go Pin-thread Ring Gauge, P6*—This gauge mates with the P5 no-go pin-thread plug gauge. In cases of dispute, this gauge may be used in gauging the product pin threads, but such use should be held to a minimum.
* No-go pin-thread plug and ring gauges, P5 and P6 are used on both sucker rods and polished rods.

2 Box Connections
2.1 Go Box-thread Ring Gauge (Checking Ring), B1—This gauge represents the minimum permissible pitch diameter of the box thread. It is used in checking the B2 go box-thread plug gauge and the corresponding working
gauge, also in checking the shoulder squareness of the working gauge.
2.2 Go Box-thread Plug Gauge, B2—Go box-thread plug gauge B2 is used on polished rod couplings and subcouplings but does not check the 9° cone. This gauge mates with the B1 go box-thread ring gauge. In cases of
dispute, this gauge may be used in gauging the product box threads, but such use should be held to a minimum.
2.3 Box-cone Ring Gauge Fitting Ring, B3—Go box-cone plug and ring gauge B3 and B4 are used on polished rod couplings and sub-couplings. Do not use on sucker rod coupling. This represents the basic box cone. It is used as the
master in establishing the standoff of the mating B4 plug gauge and the corresponding working plug gauge.
2.4 Box-cone Plug Gauge, B4—Go box-cone plug and ring gauge B3 and B4 are used on polished rod couplings and sub-couplings. Do not use on sucker rod coupling. This gauge mates with the B3 box-cone ring gauge. In cases
of dispute, it may be used in gauging the product box cone, but such use should be held to a minimum.
2.5 No-go Box-thread Ring Gauge (Checking Ring), B5—No-go box-thread ring and plug gauge B5 and B6 are used on sucker rod coupling, polished rod coupling, and sub-coupling. This gauge represents the maximum permissible pitch diameter of the box thread. It is used in checking the mating plug gauge B6 and the corresponding working plug gauge.
2.6 No-go Box-thread Plug Gauge, B6—No-go box-thread ring and plug gauge B5 and B6 are used on sucker rod coupling, polished rod coupling, and sub-coupling. This gauge mates with the B5 no-go box-thread ring gauge. In
cases of dispute, this gauge may be used in gauging the product box threads, but such use should be held to a minimum.
3 Polished Rod Pin Connections
3.1 Go Pin-thread Truncated Setting Plug Gauge, P1—This gauge represents the maximum permissible pitch diameter of the pin thread. It is used 1) in setting the mating ring gauge P2 and the corresponding working ring gauge,
2) in checking the shoulder squareness of the working gauge, and 3) for detecting wear, see I.6.
3.2 Go Pin-thread Ring Gauge, P2—P2 does not check 9° cone. This gauge mates with the P1 go pin-thread plug gauge. In case of dispute, this gauge may be used in gauging the product pin threads, but such use should be held to a minimum.
3.3 Pin-cone Plug Gauge (Fitting Plug), P3—This gauge represents the basic pin cone. It is used as the master in establishing the standoff of the mating P4 pin-cone ring gauge and the corresponding working ring gauge.
3.4 Pin-cone Ring Gauge, P4—This gauge mates with the P3 pin-cone plug gauge. In cases of dispute, it may be used in gauging the product pin cone, but such use should be held to a minimum.
3.5 No-go Pin-thread Truncated Setting Plug Gauge, P5*—This gauge represents the minimum permissible pitch diameter of the pin thread. It is used in setting the mating ring gauge P6 and the corresponding working ring gauge.
3.6 No-go Pin-thread ring Gauge, P6*—This gauge mates with the P5 no-go pin-thread gauge. In cases of dispute, this gauge may be used in gauging the product pin threads, but such use should be held to a minimum.
* No-go pin-thread plug and ring gauges, P5 and P6 are used on both sucker rods and polished rods.
