STAINLESS STEEL PRECISION SOCKET SHOULDER SCREWS

These Smooth Head Socket Shoulder Screws are precision made to very tight tolerances are suitable for use with linear motion items such as bearings. Smooth head shoulder screws have tighter shoulder diameter and shoulder length tolerances than knurled head screws making them ideal for use with ball bearings and other precision components. these popular shoulder screw sizes do not meet any specific governing body standard but are accepted sizes and dimensions in today's market place.

METRIC tolerances on the shoulder diameter are: +0.000mm to -0.025mm. The shoulder length tolerance is +0.05mm to -0.00mm. Class 6g thread fit.

INCH tolerances on the shoulder diameter are: plus zero to minus one thousandths of an inch (+0.000" to -0.001"). The shoulder length tolerance is +0.002" to -0.00". Class 2A thread fit.

Type 416 Stainless Steel is stronger and harder than 18-8 stainless steel. With no nickel and high carbon content, 400 series stainless steel has the lowest corrosion resistance among the different types of stainless steel. Not rated for tensile or Rockwell hardness.
