How to use

Remove the damaged or missing screw from the bracket or assembly using an appropriate screwdriver matched to the screw head type. Position the bracket or component in its original location and insert the replacement Unitech 381357G screw. Tighten until the bracket is secure but avoid over-torquing to prevent thread damage or deformation of plastic housings. When replacing multiple fasteners, tighten screws in a cross-pattern where applicable to maintain even seating.

Usage recommendations

Use only the specified diameter and type of screw for the device to preserve warranty conditions and ensure proper mechanical fit. If the original screw head type is unknown, verify head profile before installation to select the correct driver. For devices with glued or sealed seams, consult service documentation to avoid compromising water or dust seals during disassembly and reassembly.
