Questions about this product
- What are shoulder screws used for?
- The precision-ground shoulder acts as a built-in spacer and bearing surface. That makes these screws ideal for pivot points, hinges, and rotating parts in machinery, jigs, or robotics. The shoulder takes the load while the threaded end holds everything in place.
- Which thread sizes come in this set?
- The set covers eight metric sizes: M2, M2.5, M3, M4, M5, M6, M8, and M10. Head diameters scale from about 3.8mm on the M2 up to 17mm on the M10. Lengths vary by thread size, so check the listing for the exact size you need.
- Will these hold up outdoors or in damp conditions?
- They're made from 304 (A2-70) stainless steel, which gives strong corrosion resistance for wet or outdoor use. Tensile strength is rated at 700 MPa or higher. They also handle a wide temperature span, from -200C up to +400C.
