Grub Screws | Grade 12.9 Stainless Steel | M3-M12 Hex Socket Set

These spring-loaded grub screws have a ball plunger tip. They help with precise positioning and indexing in your projects. They're made from Grade 12.9 alloy steel. These M10 and M12 black hex socket screws handle high-stress jobs. They work where standard fasteners might not. Features and Benefits - Grade 12.9 Alloy Steel - This steel has a minimum tensile strength of 1220 MPa. The bolts can handle heavy loads and vibration. They won't stretch or break. - Black Oxide Finish - This finish gives some corrosion resistance. It's for dry or lightly oiled places. It also makes the M10 M12 black stainless steel screws non-reflective. - Spring Ball Plunger - An inside spring pushes on a small ball bearing. This lets it lock into detents or grooves. You get repeatable adjustments. - Hex Socket Drive - You can install these M10 M12 black allen bolts with a hex key. They fit well in tight spots where a wrench or socket can't go. Applications - Machinery - Use these M10 M12 black set screws to hold a pulley, collar, or gear on a motor shaft. This stops slippage under load. - Jigs and Fixtures - Use them to hold workpieces. Or, they can be an adjustable stop for repeatable cuts and assemblies. - Custom Tooling - Put them into indexing plates or rotating fixtures. The spring plunger can lock the mechanism into specific angles.
