Foreword
This
translation
has
been made based on the original Japanese Industrial
Standard revised
by
the
Minister
of
Economy, Trade and Industry through
deliberations
at
the Japanese Industrial Standards Committee
in
accordance with the Industrial Standardization Law. Consequently
JIS
B
1057
:
1994
is
replaced with
JIS
B
1057
:
2001.
In
this
revision,
this
Standard has been subjected to the formal revision
that the new specification is added to
JIS
B
1181
:
1993 as Annex 2,
following
the
revision of
JIS
B
1052
on January 20,
1998
and the
withdrawal of Annex
3
to
JIS
B
1052
dated
on
December 31, 2000.

Mechanical properties of
non-ferrous metal fasteners
Introduction
This Japanese Industrial Standard has been made based on
IS0
8839
Mechanical properties of fasteners-Bolts, screws, studs and nuts made of non-
ferrous metals
published in 1986 as the first edition, without changing the technical
contents and adding some items not specified in the corresponding International Stan-
dard. The revision
at
this
time
has
been made for the sake of formality as a result
of the revision of
JIS
B
1052
on January
20,
1998 and the withdrawal of Annex
3
(Nuts for property classes 4T to 12T)
to
JIS
B
1052
on
December 31,
2000
followed
by the development of
a
new standard as Annex
2
to
JIS
B
1181.
The parts covered by half tone dot mesh
(i-)
in
this
Standard are the matters
not specified in the corresponding International Standard.
i
Scope
This Japanese Industrial Standard specifies the mechanical properties
of
bolts (including studs), machine screws and nuts made of non-ferrous metals such
as copper, copper alloys and aluminium alloys and conforming to the requirements
for application given
in
Table
l(1)
and the test and inspection methods and the marking
of them.
Note
(1)
The
bolts,
machine screws and nuts made of non-ferrous metals which
apply
in
this
Standard are referred to hereafter
as
“bolts, machine screws
and
nuts”
and a generic term of them as “non-ferrous metal fasteners”.

metal fasteners
Remarks
1
The International Standard corresponding to
this
Standard
is
as
fol-
lows.
In addition, symbols which denote the degree of correspondence
in
the
contents between the relevant International Standard and
JIS
are IDT (identical), MOD (modified), and NEQ (not equivalent) ac-
cording to
ISODEC
Guide
21.

This Standard which specifies the mechanical properties at ordinary
temperature of the non-ferrous metal fasteners for general use does
not apply to those with special property requirements such as
corro-
sion resistance and electrical conductivity.
摘要：

JIS B1057-2001 是日本工业标准（JIS）中关于“不锈钢螺栓、螺钉、螺柱和螺母”的技术规范，该标准于2001年发布，替代了早期版本，旨在统一和规范不锈钢紧固件的材料、机械性能、尺寸公差及表面处理要求。标准主要适用于奥氏体、马氏体和铁素体不锈钢制成的紧固件，规定了不同强度等级（如A2-70、A4-80等）的拉伸强度、硬度及屈服点，同时明确了耐腐蚀性能测试方法。对于工程设计、采购及质量检验人员而言，JIS B1057-2001是确保不锈钢紧固件在建筑、化工、食品加工及海洋工程等领域安全可
