Installation for In-line Loading For in-line loading application use regular nut eye bolt or shoulder nut eye bolt. The mechanical properties to which zstm lifting eyes shall adhere are proof, breaking strength, tensile stress and strength, bend strength, impact strength, yield point, elongation, and reduction of asstm. Use a washer with approximately the same diameter as the eye bolt shoulder and the smallest inside diameter that will fit the eye bolt shank.

ASTM A – 18 Standard Specification for Carbon Steel Eyebolts

I Washers Manufacture of D. Use two nuts if thickness is less than or equal to eye bolt diameter. Application It is recommended to use shouldered eye bolts for rigging hardware, except xstm prohibited by the configuration of the item to which the eye bolt is attached.

Only one leg should be attached to each eye bolt. When more than one eye bolt is used in conjunction with multiple-leg rigging, spreader bars or lifting beams should be used to eliminate angular loading. The lifting eyes shall be manufactured as specified for the melting, atm, heat treatment, and machining processes. In the case of eyehooks for use with Grade M 4 chain, it may be necessary to use an intermediate component such as a shackle to make the connection.

Working Load Limit shown is for in-line pull. For vertical loading, eye bolts without shoulders have the same load-carrying ability as shouldered eye bolts. No other units of measurement are included in this standard. In case two or more 4a89 two eye bolts are used without spreader bars, their orientation shall be such that load is in the plane of the eyes as shown below Orientation of eye bolts. Alloy steel eye bolts are forged, quenched, and tempered with improved toughness properties, intended primarily for low- temperature applications.

Thank you for interesting in our services. One Response Jar Allah Says: The mechanical properties to which the lifting eyes shall adhere are proof, breaking strength, tensile stress and strength, bend strength, impact strength, yield point, elongation, and reduction of area.

Please copy and paste this embed script to where you want to embed Embed Script. Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length. No other units of measurement are included in this standard. Always countersink receiving hole or use washers to seat shoulder. Size px x x a49 x If the plane of the machinery eye bolt is not aligned with the sling line, add shims washers of proper thickness to adjust the angle of the plane of the eye to match the sling line as shown below.

Use one nut if thickness is more than one eye bolt diameter. Proper thread engagement must be maintained. ASTM does not atm any warranty express or implied or make any representation that the contents of this abstract are accurate, asgm or up to date. This standard specifies the basic dimensions, material, lifting capacity and conditions of use of lifting eyebolts of Grade M.

Material, Specification and Marking Eye bolts are made from forged carbon steel or alloy steel. Reeving will alter the angle of loading on the eye bolt as shown below. For more information on eye bolts dimensions and swivel hoist rings different type of rings please refer General Catalog of the Crosby Group.

Type 1, plain pattern straight shank ; Type 2, shoulder pattern; and Style B, short length. Never undercut eye bolt to seat shoulder against the load.

The lifting eyes shall be manufactured as specified for the melting, forging, heat treatment, and machining processes. Ensure that threads on shank and receiving hole are clean. Please help us to share our service with your friends.

This standard covers only eyebolts with eyes of internal diameters capable of permitting direct engagement with eyehooks of the same lifting capacity working load limit for use with Grade T 8 chain. We are a non-profit group that run this website to share documents. Eye Bolt Inspection Visually inspect each eye bolt before use. Sketches in this article are based on sketches in General Catalogue by Crosby Group.

If the eye bolt protrudes so far through the load that the nut cannot be tightened securely against the load, use properly sized washers to take up the excess space between the nut and the load as shown below. We need your help to maintenance this website.

ASTM F requires the If the hook does not go completely into the eye bolt, use a shackle to avoid loading the hook tip. When eye bolts cannot be properly seated and aligned with each other, a steel washer or spacer not to exceed one thread pitch may be required to put below the eye bolt.

Please fill this form, we will try to respond as soon as possible. This specification covers the chemical, mechanical, grain size, and dimensional requirements for weldless forged, quenched, and tempered carbon steel threaded lifting eyes formerly pertained to as eyebolts for overhead lifting.
