ASME B107.1-2002 pdf free download.SOCKET WRENCHES,HAND (INCH SERIES).
Sockets shall be heat treated to a hardness of 38 HRC 10 56 HRC.
4.5 Proof Torque
When tested as specified. tools shall withstand the proof torque specified in the applicable tables without failure or permanent deformation that might affect the durability or performance of the tools.
4.6 Nut End Socket Opening
Nut end socket openings shall be such as to ensure acceptance when gaged with gages conforming to ASME B107.17M.
4.7.1 Surface Roughness. All external surfaces shall be free from pits, nodules, forge flash, burrs, cracks, and other detrimental defects. The external forge flash shall be removed to blend smoothly with adjacent surfaces. Maximurn surface roughness values shall be determined by microinch (uin.) values. Determination of microinch values shall be taken on a representative
surface. Areas that are ground and buffed, or otherwise finished by an equivalent method, shall have a coating finish as specified in para. 4.7.2 and have a uniform surface with a maximum roughness in microinches using a 0.030 in. roughness width cutoff on the surface measuring instrument as stated herein. All surface roughness values shall be rated as the arithmetical
average. At lcast 50 of the outer longitudinal surface or major diameter shall be 30 pin. maximum, except for oxide or phosphate coated sockets. Except where knurled or grooved, the remaining exterior longitudinal socket surface shall be 150 uin. maximum. Oxide or
phosphate coated sockets shall have a maximum roughness of 150 uin. Definitions and nomenclature
used herein can be found in ASME B46.1.
(b) Nickel-Chromium Adhesion. The nickel-chromium coating shall pass the surface adhesion test as specified in the file, grind-saw, or heat-quench test of ASTM B 571.
(c) Oride or Phosphate Coating. The coating shall consist of a chemically produced oxide or phosphate, followed with a coating of a rust preventative. The customer may specify the color.
(d) Alternative Coatings. Alternative coatings may be used in lieu of nickel-chromium plating and shall be subjected to the Coating Process Qualification Test as specified in para. 5.3.
4.8 Bolt Clearance Hole
A space shall be provided for bolt clearance in all sockets except Type IIl, universal sockets (see Fig. 2).
The diameter of the bolt clearance hole shall be in accordance with that of the applicable size socket as specified in the respective tables for each class and style. The minimum depth of the bolt clearance hole shall be not less than 1.5 times the minimum depth of the nut opening as set forth in the respective tables for regular length sockets, not less than 5o of the overall length for mid-length sockets, and not less than 60% of the overall length for long sockets, as measured from the face of the nut end. The diameter and depth of the bolt clearance hole may be included in the wrench opening area if size and depth of the wrench opening are adequate to provide the bolt clearance space. When applicable, a through hole between the drive square and the bolt clearance hole is to be provided. The hole shall have a minimum diameter equal to 50% of the square drive size or equal to the bolt clearance hole diameter, whichever is smaller.
4.9 Internal Drive Opening
Internal drive openings shall be manufactured to produce a smooth, well-defined surface. The openings shall conform to ASME B107.4M.
