Small Parts Press-In Captive Stud, 303 Stainless Steel, #4-40 Threads, 3/8" Overall Length, Pack Of 100
Press-In Captive Studs embed into the panel for a secure lock
Stainless Steel is suitable where formability and cost are important considerations
Place into a punched or drilled hole
Squeeze into place with a standard press
Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Press-In Captive Studs, also known as Self-Clinching Studs, can be placed into a punched or drilled hole and squeezed into place with a standard press. The squeezing action embeds the head of the stud into the panel, creating a flush-head assembly and securely locking the stud into the panel with high torque-out and push-out resistances.
Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels.  Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316). Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to the % of Nickel contained in the material.  Â
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
