Indian Standard SPECIFICATION FOR

PLAIN WASHERS

( First Revision )

0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 9 November 1967, after the draft finalized by the Screw Threads and Fasteners Sectional Committee had been approved by the Mechanical Engineering Division Council.

0.2 This standard was originally issued in 1962. This revision incorporates the decision taken by the ISO/TC 2 Eolts, Nuts and Accessories.

0.3 This standard is based on:

Draft IS0 Recommendation No. 940 Washers for hexagon bolts and nuts, metric series. international Organization for Standardiza- tion.

Dot: ISO/TC 2 ( Secretariat-184 ) 302 First draft proposal for washers for hexagon bolts and nuts - metric series - 42 up to and including 150 mm thread diameter. International Organi- zation for Standardization.

Dot: ISO/TC 2 ( Secretariat-194) 326 First draft proposal for washers for cheese head screws - metric series - 1 up to and including 20 mm thread diameter. International Organization for Standardization.

zLl&s as ers for hexagon bolts and nuts ). Deutscher Kormen-

.

0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing the result of a test, shall be rounded off in accordance with IS : 2-1960*. The number of sign&ant places retained in the rounded off value should be the same as that of the specified value in th:s standard.

*Rules for rounding off numerical values ( rcvtkd ).

I6:2616-1967

1. SCOPE

1.1 This standard lays down the requirements for plain washers of the following types:

a) Machined washers, for precision and sdmi-precision grade of general purpose bolts and screws, in the diameter range 1.7 to 155 mm;

b) Punched washers, type A, for black grade general purpose bolts and screws, in the diameter range I.8 to 52 mm; and

c) Punched washers, type B, for slotted head screws in the diameter range I.8 to 22 mm.

2. MANUFACTURE

2.1 Material - Washers shall be made of steel, brass, aluminium or any other suitable metal specified by the purchaser.

2.2 workm*ship -The washers shall be free from cracks, burrs, pits and other defebts. The holes shall be reasonably concentric with the outer periphery. All sharp edges shall be removed.

3. DESJGNATION

3.1 A washer shall be designated by name, type, size, number of this standard and material.

Examples:

a) A machined washer of size IO.5 mm made of brass shall be designated as:

Machined Washer 1 O-5 IS : 20 16-Brass

b) A punched washer, Type B of size 14 mm made of brass shall be designated as:

Punched Washer B14 IS : 2016-Brass

4. DIMENSIONS

4.1 The dimensions for machined washers, punched washers, types A and B, shall be as given in Tables 1,2 and 3 respectively ( see P 6 to 11 ). These tables also give the size of bolt or screw for which the washers are suitable.

4.2 The other dimensional requirements for punched washers covered in Tables 2 and 3 bhall be as given in IS : 5369-1969*.’

*General requirements for plain washera and lock waahc~~.

4

IS I 2016 .- 1967

5. PmISH

5.1 l- plain washers shall be supplied in natural finish unless otherwisi specified by the purchaser. At the request of the purchaser, washers may be phosphate coated, nickel plated, tinned, galvanized, copper plated, cadmium plated, etc. The properties of the plain washers shall not, however, purchaser.

be impaired by the protective coating specified by the

6. PACKING

6.1 The plain washers may be packed as recommended below:

Sizes up to 10.5 mm In boxes of 1000 pieces

Sizes from 13 to 19 mm In boxes of 500 pieces

Sizes 21 mm and above In boxes of 100 pieces,

The plain washers may also be packed in quantities of 2 kg and 50 kg.

7. MARICING

7.1 The packages containing washers shall be marked with the &-e and manufacturer’s name or trade-mark.

7.2 BE Certification hlarking

The product may also be nlarked with Standard Mark.

‘7.2.1 The use of the Standard Mark is governed by the provision of Bureau of Indian Standards Act, 1956 and the ,Rules and Regulations made thereunder. The. details of conditions under which the licence for the use of Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards.
