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.
Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch). Zinc Plating helps to prevent corrosion.
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 (in millimeters), followed by the thread pitch (millimeters per thread), 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.
- Machine Screws are often used with nuts or driven into tapped holes
- Zinc Plated Steel fasteners are suitable where strength and corrosion resistance are primary 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

| 2 of 2 people found the following review helpful  Good screws, but 97 is not 100!, Amazon Verified Purchase This review is from: Zinc Plated Steel Machine Screw, Pan Head, Phillips Drive, M5-0.8, 10mm Length (Pack of 100) (Misc.) These screws are just fine for screwing into things. Functionally, I'm quite satisfied. But the quantity was not correct; I only received 97 screws. I ordered a pack of 100, not a pack of 97, and not a pack of "100, plus or minus 3%." And as it turned out, the project I'm working on happens to require--get this--98 screws. Such is life, I suppose. I might not have even noticed if I hadn't needed 98, or maybe I'd even be smiling if I got 103 instead of 97, but this time I got 97, so there go two stars. 1 of 1 people found the following review helpful  Well finished, By Mikul "Anomolicious" (Philadelphia, PA) - See all my reviews Amazon Verified Purchase This review is from: Zinc Plated Steel Machine Screw, Pan Head, Phillips Drive, M3-0.5, 10mm Length (Pack of 100) (Misc.) These are well-finished screws. Sadly, thanks for Amazon's vague search results I ordered the wrong size because the search function included screws that were the wrong size. Be sure to verify the size before you hit "order." great, hard-to-find product, Amazon Verified Purchase This review is from: Zinc Plated Steel Machine Screw, Pan Head, Phillips Drive, M3-0.5, 4mm Length (Pack of 100) (Misc.) I've had a hard time finding these really small machine screws locally. Am glad to have discovered them on-line through Amazon. Shipped quickly, nicely packaged ... fit the ticket perfectly! |
