Reinforcement of screw
On 2017-08-02 15:04:53
It is only a barcode in a 10 piece bag, the product size is not written.
Helisert is difficult to understand because its size is different from ordinary screws,
Please write the dimensions.

I ordered 100 pieces at 10 × 10, but it was a blessing if you made it as a bag.

About past reviews

○ There is no standard notation in the packaging bag ↑ When shipped from the manufacturer, it is stated in the box, or the bag. ○ Does sprue say that the outer diameter is large? The outer diameter (free outer diameter) before insertion is larger than the tapped hole. Increasing it makes it difficult to get out of the base material. Maximum free outer diameter of M3 is 4.11, M4 is 5.42. ○ Used to change from M8 to M6 ↑ It is an incorrect usage method. The sprue can not be used for the purpose of reducing the size of the bolt. Since the maximum diameter of the tap pilot hole of M6 is 6.42, it is too large for the pilot hole of M8. About the prepared hole, please look at the size table of the maker homepage.
Screw thread playback of female thread through

Screw playback size is M20. Although it is satisfied without problems especially after construction, the insertion is a little difficult Although I use a special tool, of course, a screw thread flies when it pushes too much, and its adjustment is hard to get used to. It is not always the place where construction is easy to do, and still fails once in several times.

Reinforcement of female thread cut into plastic products.

It looks like a stainless steel spring compressed. There is a slight gap and it is not an integral structure, so there is a doubt in strength, but if it attaches to pilot holes and install with a special tool for sprue it may be fine.
