Ordinary blind hole with a wire nut
1 Scope
This section GB/T 24425 specifies the nominal thread diameter of 3mm ~ 39mm, pitch 0.5mm ~ 4mm thick tooth series
Ordinary blind hole symmetrical surface with a wire nut.
This section provides the wire thread insert, screw GB/T 24425.5 specified tolerances for internal threads 6H, the internal thread is formed as a band
6H (GB/T 197).
This Part shall apply to the wire thread insert material to improve the low intensity of the body (such as. aluminum, magnesium alloy, copper alloy, cast iron and non-metallic) spiro
Hole intensity and improve the fatigue strength of the screw, repair damaged holes.
Note 1. This section uses the "nominal thread diameter" and "wire Lo sets of specifications" refers to the wire thread insert is screwed into GB/T 24425.5 specified internal thread after the formation
Male thread, said internal thread diameter and thread size.
Note 2. The provisions of this part of the wire thread insert installation without handles, use special tools to install cone and engaging the wire thread insert is screwed into the internal thread, internal thread formed there
Not more than 2 times the pitch of the incomplete thread.
