(a) Unassigned dash numbers shall not be used (b) Socket end of screw shall be flat and chamfered. The chamfer shall extend to the minor diameter of the thread and the edge between flat and chamfer shall be slightly rounded. (c) Location of effective locking area "X" shall be in accordance with MS 15981 except as noted herein. (d) ^PMax. = Maximum point plus minimum of 1 thread pitch. For ease in starting, locking element shall not be effective within this area. (e) Maximum major thread diameter plus .010 = Maximum ring gage diameter that locking region of part must pass through freely or with finger pressure. (f) See MS51965 and MS51966 for set screws without self-locking feature. (g) As MIL-F-18240 doesn't establish torque requirements for items above heavy line, only a positive indication of torque is required. MATERIAL: Steel corrosion resisting; Federal Standard 66, numbers 302, 303, 304, 316 or equal to or interchangeable with 16:18 Chromium Nickel-Alloy Steel. LOCKING ELEMENT: In accordance with Specification MIL-F-18240. DESIGN AND USAGE LIMITATIONS: See MS 15981. TREATMENT: Passivated (See Procurement Specifications). MAGNETIC PERMEABILITY: These screws have a magnetic permeability of 2.0 maximum (air=1.0) for a field of H=200 orsteds using a magnetic indicator per MIL-I 17214. EXAMPLE OF PART NUMBER: MS-18068-57 = 1/4-28UNF-3A x 3/4 long corrosion resisting steel cone point self-locking set screw.
