Introduction of Hex Flange Screw Manufacturer's Hexagon Socket Bolts
1. Hexagon socket bolts
The screw head of the hexagon socket screw is round on the outside, and the middle is a concave hexagon, and the hexagon screw is a common screw head.
Kind of like a hexagon. The hexagon socket screwdriver looks like an "L", cut the two ends of the hexagonal steel bar and then bend it to 90 degrees to form a
Hexagon socket head screw wrench, available in hardware store.
2. Specifications of hexagon socket head bolts
1. The inner hexagon mouth is allowed to be rounded or countersunk.
2. The end chamfer d<=M4 is the rolling end.
3. The length of the incomplete thread is U<=2P.
4. The top edge of the head can be rounded or chamfered, at the option of the manufacturer.
5. The bottom edge can be rounded or chamfered to Dw, but neither should have thorns.
6. Standard for inner six bolts: GB/T2672, GB/T2673, GB/T2674, GB/T6190 and GB/T6191
Third, the use of hexagon socket bolts
Hexagon socket head cap screws are often used in machinery, and they mainly have the advantages of being easy to fasten, disassemble, and not easy to slip angles. Allen wrench generally
It is a 90° bend. One end of the bend is long and the other is short. When screwing with the short side, holding the long side can save a lot of force and
And can better tighten the screws. The long end has a round head (a hexagonal cylinder is similar to a sphere) and a flat head, and the round head can be easily slanted in and removed.
Remove and install some inconvenient lower wrench parts. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon, and its advantages are the screw head (wrench).
The force position) is thinner than the inner hexagon, and some places cannot be replaced by the inner hexagon. In addition, the cost is low, the power intensity is small, and the precision is required.
Machines that require low use use much less hexagon socket screws than external hexagon screws.
