3.3 Design and construction. Stud terminals shall be of the design, construction, finish,

and physical dimensions as specified herein (see 3.2, figure 1, and tables I through IV).

3.3.1 Nuts, lock washers, and flat washers. Nuts, lock washers, and flat washers shall be

plated with the same finish used for the stud terminals, or shall be manufactured from a metal

that is electrolytically compatible with the stud terminals' materials. Lock washers shall conform

to NASM35338. Flat washers shall conform to NAS1149 (see figure 2). When specified, nuts,

lock washers, and flat washers shall be supplied (see 6.2).

3.3.2 Threaded parts. Threaded parts shall be in accordance with FED-STD-H28/4 and

SAE AS8879 and shall be as specified (see figure 1 and tables I through IV).

3.4 Installation tool. Stud terminals shall be installed using high-performance blind

riveters, such as the Alcoa Model 2014, the Allfast Model RV30GE, the Gage Bilt Model

GBP704F, or equivalent.

3.5 Voltage drop. When stud terminals are tested for voltage drop, the voltage drop

measured between the intersection of the stud and sleeve shoulder and the aluminum surface

where the terminal is installed shall not exceed the required value (see 4.5.3).

3.6 Current cycling. When stud terminals are tested by cycling current, the voltage drop

shall not exceed the value specified in 4.5.3 (see 4.5.4).

3.7 Thermal shock. When stud terminals are tested for thermal shock, there shall be no

evidence of cracking, loosening of parts, or other physical damage (see 4.5.5).

3.8 Vibration, high frequency. When stud terminals are tested for high frequency

vibration, there shall be no evidence of cracking, breaking, or loosening of parts (see 4.5.6).

3.9 Torque. When stud terminals are tested for torque, the studs shall not turn within the

sleeves, the terminals shall not turn within the mounting, and there shall be no mechanical

damage (see 4.5.7).

3.10 Salt spray (corrosion). When stud terminals are tested for corrosive effects of salt

spray, there shall be no exposure of base metal or blistering of plated surfaces (see 4.5.8).

3.11 Humidity. When stud terminals are tested for the effects of humidity, there shall be

no evidence of deterioration or other physical damage between electrical ground, the stud sleeve,

the mounting surface, or the terminal lug. The voltage drop shall not exceed the value specified

3.12 Bending. When stud terminals are tested by bending, there shall be no evidence of

loosening and the voltage drop shall not exceed the value specified in 4.5.3 (see 4.5.10).
