Split lock washers, inch (ASME B18.21.1): regular and high-collar spring washer ID, OD, thickness, width, #2 to 2 in

sizes

41 in table

Notes

• Inches (OD also in mm). Regular (and 'high-alloy', which AFT and the CDE sheet say is dimensionally identical): nominal size, inside diameter min and max, outside diameter max, minimum mean section thickness (T + t) / 2, minimum section width W. AFT and the CDE PDF give identical numbers for every regular row (#2 to 2 in).
• Column reading: both PDFs print a leading decimal that equals the nominal size, then two inside-diameter values and the OD. AFT lists the pair as min then max; the CDE sheet lists it larger-first with its own labels garbled, so the smaller of the pair is shown as ID min and the larger as ID max. The last two columns of each row are thickness and width: for regular washers they are 0.062 and 0.109 for 1/4 in (thickness first).
• High collar (CDE sheet, ASME B18.21.1-2009, #4 to 1-1/2): the sheet's column headers are garbled in the extracted text. Its last two numbers are shown as width W and thickness (T + t) / 2 because the radial width of a washer cannot exceed (OD − ID min) / 2, and for 1/4 in that is 0.0555 in, which fits 0.047 but not 0.078. Check this table against the standard before relying on it. Heavy and extra-duty split washers (a distributor sheet prints them) are not tabulated here.
• Not drawn: a split lock washer is a helix whose free height is not a column in any table read, so there is no honest solid; a flat ring would misstate it. Companion pages: tooth lock washers (tooth-lock-washers-inch-asme-b18-21-1), DIN 127 (spring-lock-washers-din-127-b) and Nord-Lock wedge washers.
