MS51576 Shoulder Screw Socket
MS51576 shoulder screws, sometimes referred to as shoulder bolts or stripper bolts, get their name from the unique shoulder found between the head and the threads of the screw. Lyn-Tron manufactures precision shoulder screws, so named for the high tolerance (+/-0.0005) the shoulder diameter is held to.
MS51576 socketed shoulder screws are currently offered in stainless steel, but Lyn-tron’s other precision shoulder screws are available in other standard materials, and can be customized upon special request.
All common thread sizes are stocked in Inch (4-40, 6-32, 8-32, 10-32) and Metric (M3, M3.5, M4). Precision shoulder screw Sizes come standard from 1/8” up to 1/2” shoulder dia and in Metric sizes from 3mm to 10mm diameters.
What Is A MS51576 Shoulder Screw?
An MS51576 Shoulder Screw is the unique MIL-SPEC designation for a very specific type of socketed precision shoulder screw.
MIL-SPEC designated parts were designed to meet certain US Government manufacturing standardizations for commonality, reliability, and compatibility between military systems. To ensure that they meet government standards, MIL-SPEC parts go through very rigorous quality requirements and are held to higher technical specifications.
Over the years, the MIL-SPEC designation has also been applied to direct-to-consumer parts to indicate that a fastener product has met these same standards. Parts with a MIL-SPEC designation, ensure that you receive the same exact part every time.
MS51576 precision slotted shoulder screws in particular are designated as shoulder screws with a hex-socket drive, or a head that allows for a standard hex key to be used to drive the screw into place, which are made from corrosion resistant stainless steel.
They are available with a wide range of thread sizes, thread lengths, head diameter and lengths, and shoulder diameters and lengths, providing you with flexibility for whatever your application may be.
As part of their requirements for quality and standardization, MS51576 shoulder screws are also fully DFARS compliant.
