Description
The SS304 Stainless Steel Self tapping drilling screws is a new invention in recent years. Screws are a common term for fasteners, a daily spoken word.The tail of the self-drilling screw has a tail-drilling or pointed tail shape, and no auxiliary processing is required. It can be directly drilled, tapped and tightened on the set material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and holding power are high, and it will not loosen after a long time after combination. It is easy to complete the operation by using safety punching and tapping at one time.
Uses:
It
is
a
kind
of
screw,
mainly
used
for
fixing
the
color
steel
tile
of
steel
structure,
and
can
also
be
used
for
fixing
thin
plate
of
simple
construction.
It
cannot
be
used
for
metal-to-metal
bonding
and
fixing.
Self-drilling
screw,
Material
and
model,There
are
two
kinds
of
materials:
iron
and
stainless
steel.
Stainless
steel
is
divided
into
a
variety
of
materials.
Models
are:
Φ4.2/
Φ4.8/
Φ5.5/
Φ6.3mm,
the
specific
length
can
be
negotiated
according
to
requirements.
According to the different drill tails, it can be divided into:
Round head rice / cross / plum blossom, countersunk head (flat head) / rice / cross / plum blossom, hexagon washer, round head washer (large flat head), horn head, etc.
1. Self-tapping screws: mechanical performance requirements
1. Heart hardness: standard value HRC28-38. The test is carried out on a section 1-2 times the nominal diameter from the tail. If the nominal length is too short, it can be embedded first, and then the hardness is measured.
2. Surface hardness: standard MIN HV450.
3. Carburized layer: standard 4#-6#:0.05-0.18mm, 8#-12#:0.10-0.23 mm, 14#:0.13-0.28 mm. The main purpose of carburization is to increase the surface hardness and ensure the strength of the teeth. If the decarburization is too deep and the carburization is insufficient, the strength of the teeth will not meet the requirements, that is, the teeth will be damaged during the screwing test.
