ASME B18.8.100M:2000 pdf free download SPRING PINS: COILED TYPE (METRIC SERIES)
1 INTRODUCTORY NOTES1.1 Scope
1.1.1This Standard covers the dimensional andgeneral data for coiled spring pins recognized as Ameri-
can National Standard, which are widely used in generalindustrial applications.
1.1.2 The inclusion of dimensional data in thisStandard is not intended to imply that all of the products
described are stock production sizes.Consumers should
consult with suppliers concerning the availability ofthe product.
1.2 Description
Coiled spring pins shall have straight cylindricalsides with both ends chamfered. They are available instandard duty, heavy duty, and light duty to suit variousdesign requirements.Coiled type spring pins have multi-ple walls，are spirally wrapped from strip stock to adiameter larger than basic，and are heattreated asnecessary or cold worked. Upon installation,the pin
diameters contract and the spring reaction against thesides of the hole tends to retain the pin. Dimcnsions
of coiled type spring pins are given in Table 1.
1.3 Dimensions
All dimensions in this Standard are in millimetersunless otherwise noted.
1.4 Options
Options，where specified,shall be at the discretionof the supplier，unless otherwise agreed upon by thesupplier and purchaser.
1.5 Terminology
For definitions of terms relating to fasteners or compo-nent features thereof used in this Standard，refer toASME B18.12.
1.6 Comparison With lSo 8748,ISo 8750,
and iso 8751
1.6.1 ISO 8748，ISO 8750,and ISO 8751 wereprepared by Technical Committee Iso/TC2 and pub-lished in 1987.
1.6.2 ISo 8748 covers the heavy duty，ISO 8750covers the standard duty，and ISo 8751 covers thelight duty.This Standard includes all three duties.1.6.3 At this time,all three ISO documents covercarbon steel only. This Standard covers the followingmaterials:
a) 1070-1095 carbon steel (UNS G10700-UNSG10950)
(b) 6150 alloy steel (UNS H61500)
(c) 420 corrosion-resistant steel (UNS S42000)(d) 302 corrosion-resistant steel (UNS s30200)The ISo documents detail the chemical elements ofthe materials,while this Standard identifies the materialsusing the applicable UNS designation.
1.6.4 The pin hardness in the three IsO documentsfor carbon steel is listed as 420 to 520 HV. ThisStandard lists the hardness for carbon steel and alloysteel as 420 to 545 HV. This difference has beencalled to the attention of the proper ISo committeefor resolution.
1.7 Reference Standards
Unless otherwise specified, the referenced standardsshall be the most recent issue at the time of orderplacement.
