17-4 PH Stainless Bolts: Cost-Effective and Super Strong

17-4 PH stainless bolts are made of 17-4 PH, the most widely used of all precipitation-hardening stainless steels. They are stronger than A-286 aerospace bolts and boast a 4x greater yield strength than 316 stainless steel bolts.

Though they are less corrosion resistant than Inconel bolts and MP35N bolts, they are by far the most corrosion resistant of any bolts made of standard hardenable stainless steel. They maintain their strength and hardness in temperatures as high as 572 degrees Fahrenheit but should not be used in applications that involve exposure to extremely low temperatures.

17-4 PH stainless bolts are considered cost-effective. For example, NASA encourages, whenever possible, the use of numerous 17-4 PH stainless bolts rather than fewer higher-strength bolts.

Aerospace Manufacturing creates several different kinds of 17-4 PH stainless bolts, the most popular being: MS9733, MS9734, MS9735, MS9736, MS9737, MS9739, and the MS9795 series, like the  MS9795-16 and MS9795-14. These are made of the highest quality American steel.

Procure 17-4 PH Stainless Bolts from AMI

Aerospace Manufacturing is a AS9100 and ISO:9001 accredited, QSLM approved NJ aerospace manufacturer that is trusted by some of the world’s largest aerospace OEMs to produce the most challenging fasteners — from Titanium metric fasteners and Waspaloy bolts to H11 tool steel bolts.

Our clientele includes the likes of Boeing, Bombardier, DLA, Lockheed Martin, and Sikorsky. We recently won the contract to create fasteners for Boeing’s KC-46 Pegasus tanker, and more exciting announcements are also on the way!
