Extreme-Pressure Stainless Steel Threaded Pipe Fittings
With the strength to handle extreme pressures, these fittings can be used to connect equipment in hydraulic fluid lines. 316 stainless steel fittings have excellent corrosion resistance. BSPP and metric male threads have either a gasket or a gasket and washer to prevent leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have a gasket to prevent leaks.

Compact Extreme-Pressure Steel Threaded Pipe Fittings
These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance. BSPP and metric male threads have either a gasket, or a gasket and washer, to prevent leaks.

Metric Low-Strength Steel Coupling Nuts
Often referred to as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.
Black-oxide steel coupling nuts have a dark surface color and are mildly corrosion resistant in dry environments.

Metric High-Strength Steel Coupling Nuts—Class 10
Often referred to as extension nuts, use these to connect and extend threaded rods. Made from Class 10 steel, they're about 25% stronger than medium-strength steel coupling nuts and comparable in strength to Class 10.9 bolts.
Zinc-plated steel nuts are corrosion resistant in wet environments.
