The main function of round headed square neck bolts includes connecting and fixing various structural components, ensuring their stability and safety.

Advantages and Application Scenarios of Round Head Square Neck Bolts

I. Core Advantages

Multiple material options available

Tianlong offers Round Head Square Neck Bolts in various materials: carbon steel, SS304, and SS316. Carbon steel is suitable for dry indoor environments; SS304 stainless steel is applicable to humid scenarios; SS316 is ideal for coastal and chemical industry environments.

Diverse surface treatments, enhancing product durability

Tianlong Round Head Square Neck Bolts come with options such as plain, black plated, zinc plated, yellow plated, and Hot-Dip Galvanized (H.D.G) finishes. Among them, zinc plating and H.D.G can improve corrosion resistance; black/yellow platings are more aesthetically pleasing.

Various high-strength grades available

Tianlong Round Head Square Neck Bolts are available in strength grades of 4.8, 8.8, 10.9, and 12.9. The 12.9-grade high-strength bolts can even meet the fastening requirements of heavy-duty equipment.

Round head and square neck structure

The square neck of this structure can be embedded into the groove of the connecting part, preventing the bolt from rotating and reducing the risk of loosening.

II. Examples of Application Scenarios

Construction Engineering

Scenario: Fixing of steel structure brackets and connection of precast concrete components. 8.8-grade carbon steel zinc-plated bolts with M12-M16 sizes can be selected.

Agricultural Machinery

Scenario: Fastening of components in tractors and harvesters. 10.9-grade high-strength bolts with M8-M12 sizes and black plating can be used.

Chemical Equipment

Scenario: Connection of reaction kettle pipeline flanges and fixing of storage tanks. SS316 stainless steel bolts with H.D.G surface treatment and M16-M20 sizes can be chosen, which are more resistant to acid and alkali corrosion.

Furniture Manufacturing

Scenario: Assembly of metal frame furniture. 4.8-grade carbon steel plain bolts with M5-M8 sizes can be adopted.

Outdoor Facilities

Scenario: Fixing of street lamp brackets, traffic signal lights, and installation of guardrails. 8.8-grade bolts with Hot-Dip Galvanized (H.D.G) treatment can be selected to resist outdoor wind and rain erosion.
