- Buttress Threads: Deep buttress threads further increase pull-out and back-out resistance.
- Corrosion Resistance: Excellent corrosion resistance, surpassing the FM 4470 corrosion test.
- Versatile Decks: Designed for steel decks (20 ga / 0.91 mm or 22 ga / 0.76 mm) or wood decks of minimum 15/32 in. (12 mm) CDX plywood.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
HP-X fasteners are the long-length option for through-membrane and insulation attachment where deep embedment into steel or wood decks is needed. Match the drill point to 20 or 22 gauge steel to avoid over-drilling, and always verify the specified fastening pattern before ordering. For thinner insulation stacks, shorter HP-X lengths may reduce labor and cost.
Handle fasteners carefully and use appropriate driving tools with depth control; wear eye protection when fastening overhead or on decks.
