Technical delivery conditions

Material

Eyebolts shall be made of grade C15E steel as in DINEN 10084, with an aluminium content of 0,02% to 0,05%(m /m ), or of grade A2, A3, A4 or A5 austenitic steel as in DINEN ISO 3506-1.

Eyebolts made of grade C15E steel shall be normalized to obtain an austenitic grain size finer than 5 inaccordance with DIN50601. When tested as specified in DINEN 10045-1, the impact energy, KU (ISOU-notch test piece), shall be 40 J.

For eyebolts made of austenitic steel, solution heat treatment is required.

NOTE: Property classes as in DINEN ISO 3506-1 are not specified here since testing of the relevant mechanicalproperties is not possible.

4.2Workmanship

Eyebolts shall be cleanly drop forged in one piece. Tolerances on the dimensions of unmachined parts and onresidual flash and mismatch shall be as specified in DINEN 10243-1. The general technical delivery conditionsspecified in DINEN 10254 shall apply.

Limits for surface discontinuities of the threaded shank shall be as given in DINEN 26157-3. Eyebolts made of stainless steel shall be passivated as specified in DINEN ISO 16048.

Eyebolts of sizes exceeding M36 may be provided with a centre hole in the upper part of the eye.

4.3Screw threads

Threads shall be produced to tolerance 6g as in DINISO 965-2 for thread engagement group N as specified inDIN ISO 965-1.

5Minimum breaking load

Table 2:Minimum breaking load

When subjected to proof loading, the minimum breaking load of eyebolts shall be as specified in table 2.

Testing

Proof loading

Compliance with the requirements specified in clause 5 shall be verified by proof loading carried out on twopairs of eyebolts, fitting the samples axially in the grips of a tensile testing machine. The diameter of the pinto receive the bolt shall be equal to 1 × k to 1,5 × k .

6.2Inspection

Each eyebolt shall be visually checked for the features specified in subclause 4.2. For eyebolts made of stainlesssteel, this check shall be carried out after passivation.

8Marking

Eyebolts shall be permanently and legibly marked with the manufacturer’s trademark, the symbol denoting thematerial grade (e.g. C15E or A2), and with any details required by statutory regulations.

9User information

Eyebolts shall be supplied with the relevant information for their safe and proper use. This information shallinclude at least the details given in Annex B.

Annex A

Lifting capacity

The maximum lifting capacity (safe working load) of eyebolts used with single-strand or double-strand slingsis given in table A.1. The values are based on the minimum breaking loads specified in table 2, taking intoaccount a safety factor of 6.

Annex B

User information

Eyebolts conforming to this standard are primarily intended as permanent attachments on equipment such asmotors, control cabinets, gear boxes, etc. When used as temporary attachments on larger objects such as largetools for transportation only, the next largest thread size should be used.

The safe working load values given in table A.1 are based on the following assumptions:a) The eyebolt is firmly screwed down and the collar sits evenly on the contact surface.

b) The material of the equipment is capable of accommodating the stresses induced without any deformationliable to impair safety.

c) Tapped holes have a threaded length sufficient to ensure that the eyebolt shank is fully engaged and thecollar fully seated.

In eyebolt/nut assemblies with clearance hole, a washer should be used.

The values given for eyebolts used with double-strand slings (cf. table A.1, line 2) apply only if the angle betweeneach sling branch and the vertical does not exceed 45°. Larger angles and any lateral loading of eyebolts shouldbe avoided.

Before being used, eyebolts should be checked for correct seating and apparent damage (e.g. corrosion,deformation).

Deformed eyebolts should be discarded.
