MS20001 hinges are extruded from aluminum alloy with the option of plain, anodized or chemically surface treated finishes. The MS20001 series hinges are typically manufactured in continuous lengths and then cut to size to meet length requirements. In addition, the full MS20001 series part number is stamped at regular intervals along the length of each hinge to make identifying replacements easier.
Compared to other mil-spec parts the MS20001 series has a relatively complex part numbering system. One of the key features of the part numbering system is that the last dash number indicates the length of the hinge in inches to the 100th decimal place. For example MS20001PH6-7200 has a length of 72 inches while MS20001PY16-2150 has a length of 21.5 inches.

The MS3498 captive panel screw assembly includes a captive screw, a flange, and a collar. MS3498 panel screw assemblies in conjunction with captive nuts per MIL-N-45938/11 are designed to secure printed circuit boards (PCBs) to panels. When disengaged from the captive nuts, the captive screws can also be used for lifting the PCB.
The MS3498 collar and flange are made from aluminum alloy with the options of black lusterless, gray lusterless, or clear anodized finishes. Captive screws are made from stainless steel with the option of black lusterless or gray epoxy paint finishes.

Note: The MS3498 has been superseded by NASM3498 as of November, 1998. However the part numbers have remained the same.
MS21914 pressure seal caps are commonly used on aerospace applications to securely close tubing. MS21914 series caps feature a raised hex nut to allow for maximum torque when tightening. In addition, the MS21914 caps have a retainer ring on the end to prevent the loss of the cap upon removal. MS21914 pressure seal caps are available in carbon steel, aluminum alloy, stainless steel, and titanium alloy. The specification notes that titanium alloy is not recommended for use in oxygen systems.
Each dash number after the series number (MS21914) indicates a different size with other characters indicating the material and finish. For example, part number MS21914-16 is designed for 1 inch diameter tubing and has an inside diameter (ID) of .906 inches, a length of 1.189 inches, and is made from carbon steel.
Check out the MS21914 spec sheet for more details MS21914 tube caps.
MS35691 jam nuts are mil-spec nuts specifically designed for low profile applications and often used as locknuts. MS35691 nuts are available in carbon steel, corrosion resistant steel (stainless steel), and brass. Coating options include cadmium, black oxide, phosphate and nickel. MS35691 thread sizes range from .250 inches to 3.00 inches with nut thickness running between .150 and 1.763 inches.
The MS35691 specification was reactivated as of March, 2005 after the original 1984 spec had been discontinued. The current revision is revision E. To learn more technical details view the MS35691 spec sheet.
MS20392 series pins are referred to as clevis pins because of the drilled hole in the shank. The hole allows the pin to be secured in place by inserting a split pin (cotter pin) into the hole. MS20392 pins are available in three material options: steel alloy, corrosion resistant steel (stainless steel), and titanium alloy. Finishes include cadmium, chrome, solid film lubricant, and passivated. MS20392 pin diameters range from .125 inches to 1.00 inches. while lengths range from .219 inches to 4.281 inches.
For further specifications and part number configuration view the MS20392 spec sheet.
Note: Specification MS20392 revision F has been superseded by NASM20392 as of June 21, 1999. However, MS20392 series part numbers have remained the same.
MS21043 self-locking nuts are manufactured from corrosion heat resistant steel with silver plating on all threaded surfaces and optional silver plating on all other surfaces. The MS21043 series locknuts feature a low profile optimized for use in tight spaces as well as a ring base to eliminate the need for washers. Like other locknuts the MS21043 series is designed to stay securely fastened despite heavy vibration and constant movement.
For complete specification information view the MS21043 spec sheet.
Note: Specification document MS21043 revision E has been superseded by NASM21043 but the part numbers have remained the same.
MS51844 sleeves are used to to bind wire ropes together and create anchor loops (pictured below). The MS51844 wire rope sleeves are made from type 304 corrosion resistant steel (stainless steel) or type 102 copper alloy. MS51844 sleeves accept nominal cable sizes ranging from 1/32 to 3/4 inches.
Once crimped MS51844 wire rope sleeves provide reliable clamping with breaking strength ranging from 110 lbs to 53000 lbs depending on the sleeve specifications.
To see detailed technical specifications view the MS51844 spec sheet.
MS51957 machine screws feature a pan style head with a philips (cross-recessed) drive. The MS51957 series are fabricated from corrosion resistant steel (stainless steel) and are either passivated or coated in black oxide. Screw lengths range from 1/8 inch to 3 inches.
MS51957 machine screws come in a variety of configurations with each call out after the base series number indicating a specific configuration. For example, in part number MS51957-14B the “14” indicates a .312 inch length while the “B” denotes a black oxide coating.
The MS51957 series machine screws replace many of the MS16200, MS35233, MS35216, AN515, and AN526 series machine screws.

MS21076 series nut plates (plate nuts) feature a floating nut with self-locking capability. The floating nut allows the nut the move slightly providing for larger positioning tolerances. MS21076 nut plates have two lugs on either side of the nut so that the plate nut can be securely anchored in place using rivets. The MS21076 series is manufactured from corrosion resistant steel with a 49 HRC max hardness and features either dry film lube or silver plating depending on the configuration. MS21076 plate nuts are commonly used in aircraft but may be found in other vehicles as well.
For detailed technical information and part number configurations view the MS21076 spec sheet.
Note: Specification document MS21076 revision H has been superseded by NASM21076 but the part numbers have remained the same.
