SOPREMA HD Insulation Fasteners #15 Heavy-Duty Roofing Screws, 2 in. to 20 in., Mill Finish, Boxed
Soprema #15 HD fasteners are heavy-duty roofing screws engineered for fastening insulation, SBS membrane plates and batten bar seams, and metal edge or termination bar securement across a range of substrates. Sold by the box, the line spans 12 mill-finish lengths from 2 in. to 20 in., with box counts from 1,000 down to 250 pieces to match fastener size.
Key Features:
- Superior pullout: The #15 HD design delivers superior pullout performance in a variety of roof substrates.
- Back-out resistance: A specifically designed thread increases resistance to back-out after installation.
- Wide length range: Twelve lengths from 2 in. to 20 in. cover thin to thick insulation assemblies and deeper substrates.
- Multi-application: Approved uses include insulation attachment, SBS membrane plate and batten bar seams, and metal edge or termination bar securement.
- Third-party approvals: Listed with FM Approvals, ICC-ES, Miami-Dade County and Florida State-Wide Approval.
- Bulk boxing: Boxes are packed to suit fastener length, from 1,000 pieces for short lengths to 250 pieces for the longest.
- Mill finish: All sizes are supplied in mill finish for concealed, fastener-covered roof assemblies.

Coverage & How Much You Need:
Fastener quantity depends on assembly design: for typical insulation attachment, plan fastener density per the membrane manufacturer's wind-uplift requirements and divide the roof area by that spacing to determine boxes needed. Longer lengths are required as total insulation thickness increases.
Fit and Compatibility:
Use with Soprema SBS-modified bitumen membrane systems, matching Soprema plates and battens, and compatible metal edge and termination bar details. Fastener length must be selected so the screw penetrates the structural deck to the depth required by the wind-uplift design.
Frequently Asked Questions (FAQ):
Q: How many fasteners come in a box?
A: Box counts vary by length: 1,000 pieces for 2, 4 and 5 in.; 500 pieces for 6, 7 and 8 in.; and 250 pieces for 10 in. through 20 in. lengths.
Q: Which length should I choose?
A: Choose a length that equals insulation thickness plus membrane/plate buildup plus the required deck penetration specified by your fastening pattern or uplift calculation.
Q: Are these approved for high-wind areas?
A: The line carries FM Approvals, ICC-ES, Miami-Dade County and Florida State-Wide Approval listings; verify the specific approval report for your project's design pressure.
Q: What applications are they rated for?
A: They are engineered for insulation attachment, SBS membrane plate and batten bar seam applications, and metal edge or termination bar securement.
Q: Do they resist backing out?
A: Yes, the thread design is specifically engineered to increase back-out resistance after installation.
Q: Are plates included?
A: No, this line is the fasteners only; matching plates and batten bar are ordered separately.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the fastener length to the full assembly stack, insulation plus any cover board, and confirm deck type before ordering, since pullout capacity varies by deck. For tall insulation assemblies, step up to the 10-20 in. sizes rather than overdriving shorter screws. Pair with Soprema plates for membrane attachment and use termination-bar lengths at edges and base flashings. Always install a test fastener to verify embedment before committing the field.
Wear gloves and eye protection when handling and installing sharp roofing fasteners, and follow the project's approved fastening pattern for wind-uplift compliance.
