Metric bolt conversion data for industrial bolts/rods, machine screws and small diameter fasteners from Elgin Fastener Group includes metric to standard bolt conversions. The least input increment (smallest programmable value) is usually 0.0001 inch in the imperial system and 0.001 mm in the metric system, though there are high-precision machines that measure to 0.00001 inch and 0.0001 mm. h�bbd```b``Z"�@$�f�2,&����`�b`� ,�&9�$3��n� " ��5A��\�x(�4���IF��@���CL@���a`������� �K ��T�rd��l�Ø_����h:�����2ڴ�B����E�,���C�r��GoAa%PU�����Q�����U��F�t�uEa�������ZPߠ�ҡ��CgJ�����ܩ�=����?X��������h�UL���Υb��N�B�K��"���&��z����g6ѽ�A��gꁈ8�����'`�Ҧl��� �2w�.

Bolt Thread Sizes. G-Wizard has a bunch of them in its database. Whitworth thread is coarser than a BSF of the same diameter,but the same spanners are used on both ranges,and are often marked with both Whitworth and BSF sizes .A whitworth spanner or socket is larger than one marked with the same size in BSF for example a 1/4 inch whit is the same physical size as a 5/16inch BSF. 1/2" AF (across flats) - 5/16" dia, Please only order by specifying thread diameter. Due to the differences in thread angles and pitches, the thread sizes shown below are not directly interchangeable with each other. 10 0 obj <> endobj Thread Form Data Tapping Drill Clearance Drill Size O/Diameter Core Pitch Depth Radius Effective Dia T.P.I Dec / Met / Frac Dec / Met / Frac 0BA 0.2362 0.1890 0.0394 0.0236 0.0072 -- 25.38 0.2008 - 5.10mm 0.2362 - 6.00mm xeçõ@œæeh÷ÞÖÍ8/ioG$[’Þ½ŸÕ¼{(숮™æí4­]N½¸è^º¼4Ìc¿zÒ÷ÛÞ¾.ÿpZvŤ¼|¼6YÐÿ|È¢Æ,_ÞIn¥ój›/YúXT;U[,~裏¡ Õ0´Ç*£Ó?Nÿ(èÿʓ™èYË^ÑvªŽ7F{ùäU(ÎÎ;ᤤ½ó¼„îÙU ÔNòa p1,ó1}Ö]}.

For screws which have a hex head such as coach screws, the size is quoted as an ISO Metric which is the number starting with ���M���. Metric & Imperial Thread Size Guide Thread sizes are intended to be used as a guide and are for reference purposes only. The information contained upon this page is supplied in good faith, and to the best of my knowledge is accurate. British Association screw threads, or BA screw threads, are a largely obsolete set of small screw threads, the largest being 0BA at 6 mm diameter.They were, and to some extent still are, used for miniature instruments and modelling. Likewise, thread pitch is specified in threads per inch in the imperial system and in millimeters in the metric system. The Y axis is measurement in millimeters. Bolts are a type of essential fastener that often assembled with nuts. %%EOF Drill sizes are for 75% depth of thread.

This section contains tables of sizes for metric thread hardware. They are unusual in that they were probably the most "scientific" design of screw, starting with 0BA at 6.0 mm diameter and 1.0 mm pitch and progressing ��� Choose which thread you want. 3mm = thread length (3.00 to 4.60) = average overall screw length in that category including the head. In the lower left corner is a convenient table of tap drill sizes with a column showing thread percentage.

Glossary Thread calculator: All calculated results are based on; Basic outside diameter, number of threads per inch, series designation and class tolerances. The X axis is the gauge size. Hardware Sizes: Metric Screw Thread. For instance, a UTS thread of 1/4-20 will have a diameter of 1/4 inch, and 20 threads per inch. UNF bolts are often referred to by their spanner size rather than diameter i.e. The algorithms used for this calculator are based on the "my" best interpretation of the ANSI/ASME B1.1-1989 specification. This table is only to help find a nearest equivalent sized fastener. 46 0 obj <>stream Coarse pitch threads are preferred and should be used whenever possible, as stated in ASME B1.13M. Using a bolt with the right 0 If you are new to our website please see Sizing Notes However it is actually a metric based standard that uses a 47.5° thread angle and has its own set of head sizes. The following table of thread sizes for coarse and fine pitch thread was created using the standard sizes from ASME B1.13M.

You will note the overlapping sizes, this is due to the variance in head thicknesses. For thread sizes smaller than 1/4 inch, a numerical size such as No.1 (Or #1) is used. )OBÓæՈ&9F.Ãi׿5,ò¶Mó†õxœÓùåä. 1.Thread sizes in inches are specified by diameter and threads per inch. endstream endobj 11 0 obj <> endobj 12 0 obj <> endobj 13 0 obj <>stream endstream endobj 14 0 obj <>stream Imperial Spanner Sizes and Threads Conversion Charts Many manufacturers still market screws that way, but for those of you who find it frustrating buying in metric, here���s a ��� Working directly with two factories, We supply some of the largest outlets in the UK and Europe with high quality, BA, BSF, BSW, UNF, UNC and Metric threaded hardware. �����Y�X�8K�]~���KmW�ʕ��7N3:�H1��M`�kL8,���q5�UV,��s�!s�c��.��U�μ���,�]�r�$�� e�'��(]��!ֿ�p>��Kh$�׎:ǣ@S��,�r�&R�(��z:}~m�aǐz�O��},f���u�:�U����˯E�A�����q��g���Q%8�����Q�q���Y�)�l�dU�z7iAxp�q3�Y��"�_@uk�ۛ�\}6w7���E�� %�N�|s�B�Y���̓�C�Cj)H�W��,R>/~GB56��f�(C���N�j����o��n��g�2�|w;ϐB?A�������[���5�1�m��B�7�E�w�ⵔP���J쫾@!tpp���B�B� ���%���`�x�Q��#�Mz_�'���lr���qt�'����QSb�������zA�?
