The Easy Way To Purchase Heavy Duty Eye Bolts |
Posted: September 16, 2020 |
The shoulder helps the heavy duty eye bolts support angular loads caused by tension on the rope or cable. Many manufacture stainless steel eyebolts in both 316 stainless steel and steel, in zinc-plated, electro-polished, or mill finishes. The large diameter eye bolts come with inner opening diameters in the range of 0.25" to 2.0", with shanks from 1.0" to 4.0" in length. Eyebolts in Cold Weather Applications As described in part I in this series there are various governing standards that apply to eye bolts. The ASME (American Society of Mechanical Engineers) describes how to safely use various products. There are three standards within ASME that apply to eye bolts: ASME B18.15 for imperial threaded eye bolts, ASME B18.15M for metric threaded eye bolts and ASME B30.26 for Rigging Hardware of which eye bolts are a part of the adjustable hardware section. ASTM is a standards body that determines material requirements and establishes testing protocols to ensure compliance with ASME standards. The two testing standards that apply are ASTM A489 for Carbon Steel Lifting Eyes and ASTM F541-12 Standard Specification for Alloy Steel Eye bolts. The ASME B30.26 standard is applicable only to carbon steel eye bolts specifies that carbon steel eye bolts are only to be used above -1°C. For environments below -1°C the standard is ASTM F541-12. In order to achieve certification with this standard the eye bolt must be made of alloy steel and be permanently marked with the letter A denoting it as cold weather specific. Therefore, there is no situation in which a carbon steel eye bolt can be certified for safe use below -1°C. If any doubt exists regarding the possible lowest working temperature a rated alloy steel eye bolt should be used.
