The 5/16"-18 x 2" Through-Bolts are designed for mounting standard door pulls on glass doors. These bolts are compatible with glass thicknesses ranging from 3/8" to 3/4". Featuring a flat head design, these through-bolts provide a stable connection for door hardware. The set includes two screws per pack, and they are ordered by the pair. The finish is satin anodized, offering a neutral appearance for various architectural applications. These bolts are suitable for use in commercial door pull installations on glass panels. The through-bolt mounting adapter bolt allows for the attachment of door pulls directly through the glass, which is a common requirement for frameless glass doors in storefronts and commercial buildings. The 5/16"-18 thread size is a standard specification for this type of hardware, ensuring compatibility with a wide range of door pull handles. The 2" length of the bolt accommodates the specified glass thickness range, allowing for a proper fit during the installation process. These bolts are intended for use in pairs to secure the pull handle on both sides of the glass door. The satin anodized finish is applied to the surface of the bolts, providing a consistent look that coordinates with other architectural hardware components. This product is designed for use in professional door hardware installations where a through-bolt connection is required for the mounting of pull handles on glass surfaces.
