Mule-Hide 3 in. #15 EHD Fasteners, 1,000 Per Box

The Mule-Hide EHD Fastener is a 3 in. long #15 fastener supplied 1,000 per box. Built as a self-drilling screw-type fastener, it is used in low-slope roofing assemblies where a heavy-duty fastener is needed to anchor insulation and membrane components to the deck.

Key Features:

• 3 in. length: The 3 in. length reaches through thicker insulation build-ups into the deck.
• #15 size: A #15 fastener size is used in heavier-duty attachment applications.
• Self-drilling: Categorized as a self-drilling screw, it drives into steel deck without a pilot hole.
• 1,000 per box: One box holds 1,000 fasteners for larger jobs.
• Low-slope roofing: From Mule-Hide, a commercial low-slope roofing products brand.

Coverage & How Much You Need:

Fastener coverage depends on the specified attachment pattern; the 3 in. length is typically selected where insulation thickness requires deeper deck penetration, so count fasteners per the system’s uplift-derived pattern to size the order.

Fit and Compatibility:

Intended for use in low-slope roofing assemblies such as Mule-Hide systems over steel deck; confirm the required plate and fastener combination with the system specification. Plates and other components are sold separately.

Frequently Asked Questions (FAQ):

Q: What is included in one box?
A: One box containing 1,000 Mule-Hide 3 in. #15 EHD fasteners.

Q: When should I pick a 3 in. fastener?
A: Choose 3 in. when the total insulation plus any boards require a longer screw to embed adequately in the deck; verify the total build-up thickness before ordering.

Q: Does it drill its own hole?
A: It is listed as a self-drilling screw, so it can be driven into steel deck without pre-drilling when used with the appropriate screwgun.

Q: Is a fastening plate required?
A: Depending on the assembly, EHD fasteners are often used with matching plates; follow the roofing system specification for the approved combination.

Q: What tool drives these?
A: A screwgun or auto-feed tool capable of driving self-drilling roofing fasteners of this diameter and length.

Expert Verdict Reviewed by the SuperArbor Pro Desk

Select the 3 in. EHD fastener when the fastener must span multiple insulation layers and still achieve good deck embedment; measure total build-up thickness first. Drive with a screwgun set to seat flush without over-torque, and use the specified plates where the assembly calls for them to spread the load across the insulation.

Wear eye protection and gloves when driving long self-drilling screws; screws and debris can be ejected during fastening.

Add Mule-Hide 3 in. #15 EHD fasteners to your order for heavy-duty insulation attachment.
