Rockwood SP1064 Single Cone Head Machine Screw | 5/16-18 x 1-1/8"

The Rockwood SP1064 is a high-strength, precision-engineered fastener designed specifically for Type 13HD back-to-back mounting on glass doors. Built for durability and superior grip, this Single Cone Head machine screw is the essential component for securing heavy-duty pull handles to 1/2" glass door panels. Its robust design ensures a sleek, functional installation that meets the demands of high-traffic commercial environments.

Heavy-Duty Engineering for Glass Entrances

• Type 13HD Mounting Specialist: Specifically crafted for Heavy-Duty (HD) back-to-back applications. This screw provides the structural foundation required to link two handles through a glass lite securely.
  
• Optimized for 1/2" Glass: With a 1-1/8" thread length and 1-11/16" overall length, this fastener is precision-sized to provide maximum thread engagement for standard half-inch thick glass doors.
  
• High-Torque Hex Drive: Unlike standard Phillips head screws, the SP1064 features a hex drive (requires a 3/16" Allen wrench), allowing for positive tightening and preventing the "cam-out" often associated with heavy-duty architectural hardware.
• Superior Shear Strength: The larger 5/16-18 thread pattern offers significantly higher strength and stability than standard 1/4-20 hardware, making it ideal for oversized or high-frequency pull bars.
• Precision Conehead Seat: The tapered conehead design ensures a perfect, self-centering seat within the handle mounting post, eliminating wobble and protecting the glass from uneven pressure.
