Steel Self - Tapping Thread Insert M4 M5 M6 302 Type For Wood
Insert
Introduction
Self-tapping threaded sleeves are also called self-tapping threaded
sleeves. They are a new type of fastener that enhances the thread
strength. Self-tapping threaded sleeves have tooth patterns on the
inside and outside. They are embedded in softer materials such as
plastic, aluminum alloy cast iron, and copper, which can form
relatively High-strength internal threaded holes, self-tapping
threaded sleeves (self-tapping braces) can also repair damaged
internal threads.Self-tapping screw sets (self-tapping braces) are
now widely used in the automotive industry, rail car industry,
shipbuilding industry, household appliances, construction
machinery, office machinery, electronic products, engineering
plastics, high-end modular furniture, aluminum die-casting and
other industries.
Use
Self-tapping threaded inserts are self-tapping threaded inserts
with slots or holes. Slotted threaded threaded inserts are
recommended for most applications. On some materials, this threaded
sleeve provides the perfect specific thread lock function. If it
still does not work, it is generally recommended to use the 307/308
type, which has made a major breakthrough in the difficulty of
material cutting. This product not only has a very thick wall, but
also has three circular holes with cutting ability scattered on the
wall. The 307/308 product is especially suitable for the case where
the material thickness is not too wide.
Material
The materials used in domestic self-tapping screw sleeves are
generally carbon steel and stainless steel.
1. Carbon steel: Color-plated zinc, suitable for surface
carburizing heat treatment on aluminum alloy, copper alloy, plastic
and other substrates with low engineering strength.
2. Stainless steel SUS303 (304, 316, 316L): suitable for surface
passivation treatment on cast iron and other products with higher
strength.
