Hardware Screws

Steel structure bolt: a high-strength bolt and also a standard part. It has good fastening performance and is used in steel structures and engineering to fasten.

High-strength bolt specifications and models are mainly: m8, m10, m12, m14, m16, m18, etc. The grade standards can be divided into three grades: 8.8, 10.9, and 12.9. If it is an external thread nut, the models are mainly M16x90, M16x95, M16x80, M20x90, etc. If it is a hexagonal bolt, the models are mainly M16x70, M12x50, etc.

Drill tail thread: mainly used for fixing colored steel tiles of steel structures, and can also be used for fixing thin plates of simple buildings

Rivet: a single-sided riveted rivet used for fixing.

Expansion screws: The principle of expansion bolts is to drive the expansion bolts into the holes on the ground or wall, and then tighten the nuts on the expansion bolts with a wrench. The bolts move outwards, but the metal sleeves outside do not move. Therefore, the big head under the bolts expands the metal sleeves to fill the entire hole. At this time, the expansion bolts cannot be pulled out.

Double-headed wire: Tie rods refer to common components in steel structures. The main material is generally Q235 wire, and the diameters of φ12 and φ14 are more common. Tie rods are the out-of-plane support points of purlins, so the tension on the tie rods is the horizontal load borne by the purlins. The arrangement of tie rods should take into account the influence of wind loads, calculate the cross-section of the tie rods according to the actual force, and meet the structural requirements.

Turnbuckles: Used to tighten the wire rope and adjust the tightness. It has a variety of specifications and models, and can be selected according to different usage scenarios and needs.
