- Machine Screws are often used with nuts or driven into tapped holes
- Stainless Steel is suitable where formability and cost are important considerations
- Pan head allows for higher tightening torques
- Phillips drive is designed to cam out under too much torque
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Product Description
Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.
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.
Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.
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.

Hard to Find,
Amazon Verified Purchase(What's this?)
This review is from: Stainless Steel Machine Screw, Pan Head, Phillips Drive, #8-32, 2-1/4" Length (Pack of 100) (Misc.)
Needed a small quantity of #8-32, 2 1/4" machine screws for a project and surprisingly couldn't find them in any Home Depot, Lowe's, Ace, True Value, etc. stores in two states. Figured I'd have to cut down something longer and before going to buy some 3" ones I'd seen, decided to check Amazon just for the heck of it, and almost couldn't believe I found them here. They're exactly what I needed, reasonably priced, the quality is excellent with nice clean cut threads, smooth pan head and clean cut drive slots, and they're stainless steel to boot. Even found the stainless steel nuts I needed for them here, too. Thanks, Amazon!

One heck of a screw,
By S. "strap" (Honolulu, HI) - See all my reviews
This review is from: Stainless Steel Machine Screw, Pan Head, Phillips Drive, #4-40, 1/4" Length (Pack of 100) (Misc.)
Stainless Steel 18-8 Pan Head Phillips Machine Screw IFI 4-40 x 1/4" Length are a great value. Here you can get a pack of 100 for only $3.75...that's only $.0375 per screw!!! We all know the screw as a simple machine used to translate torque into linear force. I'd like to define it as an incline plane simply wrapped around a shaft, and this one has a pan head to boot! Its low disc with chamfered outer edge is far superior to the button or dome heads cylindrical rounded top.

Great price,
Amazon Verified Purchase(What's this?)
This review is from: Stainless Steel Machine Screw, Pan Head, Phillips Drive, #10-24, 5/8" Length (Pack of 100) (Misc.)
This product is not available locally where I live,but it is 1/3 the price of 1/2 inch screws which are!
