Wing Self Drilling

Short Description

Brand:- HP or any general.

Fastening through layers matters more than most people realize, especially when insulation, sheeting, and steel framing are all stacked together in a single fixing point. Self drilling screws with wings are built to handle exactly this kind of layered assembly. The small wings positioned just below the drill tip cut an oversized hole through the outer sheet or insulation blanket first, clearing a path so the screw doesn't drag material down into the fixing point. Once the wings reach the steel purlin underneath, they shear off, letting the screw's main thread engage the metal cleanly. A winged self drilling screw is particularly useful in roofing systems with insulation layers, where a standard screw would otherwise bunch up material and compromise the seal at the fixing point.

Material: Case-hardened Carbon Steel
Drill Capacity: Suited for steel purlins typically 3mm to 12mm thick
Thread Type: Self-tapping thread with wing-assisted drilling section
Size Range: 5.5mm to 6.3mm diameter, with extended lengths for insulated assemblies
Wing Design: Reaming wings positioned just below the primary drill point
Surface Finish: Zinc Plated, Ruspert Coated, or other corrosion-resistant coatings
Standards: ASTM, DIN, and applicable roofing industry specifications

Key Features

Wings positioned below the drill tip to ream oversized holes
Prevents material buildup when fastening through insulated layers
Wings shear off automatically once steel is reached
Hardened drill point for reliable penetration into structural steel
Self-tapping thread for clean engagement after wing breakoff
Compatible with insulated roofing and cladding systems
Sealing washer options available for weatherproof fixing points
Coated finishes available for improved corrosion resistance

Applications of Wing Self Drilling

Insulated roofing systems with sheeting over insulation
Industrial shed and warehouse roofing
Cold storage building construction
Metal roof and wall cladding with foam or fiber insulation
Pre-engineered building assemblies
Agricultural building roofing
Commercial building envelopes
Structural steel retrofitting with added insulation layers
Portable cabin and container roofing
General multi-layer metal building fastening

Advantages of Wing Self Drilling

Prevents insulation or sheeting material from clogging the fixing point
Reduces installation issues on multi-layer roofing systems
Provides a clean thread engagement into structural steel
Speeds up fastening on insulated cladding projects
Maintains a tighter seal at each fixing point
Performs reliably across varying purlin thicknesses

Why Choose Genuine Enterprises

Genuine Enterprises manufactures wing self drilling screws designed for the layered fastening challenges found in insulated roofing and cladding systems. Every batch is checked for wing consistency and drill point hardness, since poor wing performance can lead to clogged fixing points on site.

Roofing contractors working with insulated panel systems have come to rely on us as a wing self drilling screw supplier in India, since we stock a range of lengths suited to different insulation thicknesses. Our team can also help match the right wing and drill point combination to the specific roofing assembly being installed.

1.What is a winged self drilling screw used for?
It's used to fasten through layered assemblies, such as insulation and roof sheeting, into a steel purlin, without the outer material bunching up at the fixing point.

2. How do the wings on the screw work?
The wings ream an oversized hole through the outer layers before shearing off once they reach the steel, allowing the main thread to engage the purlin cleanly.

3. Are self drilling screws with wings suitable for insulated roofing?
Yes, they're specifically designed for insulated roofing and cladding systems where standard self-drilling screws can struggle with material buildup.

4. What thickness of steel can these screws drill into?
Most winged self drilling screws are rated for steel purlins ranging from around 3mm to 12mm, depending on the specific screw design.

5. Do these screws come with sealing washers?
Many versions include EPDM or neoprene sealing washers to help maintain a weatherproof seal at each fixing point.
