What is a Solar Hanger Bolt with Self-Drilling Tip?

Solar Hanger Bolt with Self-Drilling Tip is a hybrid fastener that combines three critical functions:

Self-Drilling Tip: A drill point (like a Tek screw) that eliminates the need for pre-drilling a pilot hole. It drills its own hole through the steel.

Bolt Threads (Upper): Machine threads on the top portion, designed to accept a nut. This is what secures the solar rail bracket or mounting foot.

Fastening Threads (Lower): Coarse, spaced threads (like a lag bolt or wood screw) that are designed to tap and grip into the underlying structural material. In the case of steel, these threads “tap” into the drilled hole and create a strong, secure hold.

Essentially, it drills, taps, and fastens in one operation.

Key Advantages of Solar Hanger Bolt with Self-Drilling Tip

Speed of Installation: The biggest advantage. No need to switch between a drill bit and a driver bit. Drills and fastens in one step, drastically reducing labor time.

High Strength: Provides excellent pull-out (uplift) resistance, which is critical for solar arrays facing high winds.

Seam Integration: Many are designed to be used with specialized sealing washers (EPDM or metal) when penetrating a roof, creating a watertight seal.

Vibration Resistance: The combination of the nut on top and the threads engaged in the steel below creates a very secure, vibration-resistant connection.

Conclusion: Solar hanger bolts with self-drilling tips are a premium, efficient, and strong solution for attaching solar mounts to steel structures. Our #Solar Hanger Bolt with Self-Drilling Tip is is designed with self-drilling point and an all-in-one fastener designed specifically for speed and strength in solar installations on steel purlins, standing seams, or corrugated metal roofs.
