Kwikset 86129-006 Thick Door Screw Pack 660 870

Product Description

The KWIKSET 86129-006 is a thick door screw pack designed to provide the correct fastener length for proper installation of Kwikset 660 and 870 series deadbolts on thick door applications. Standard screw packs are sized for typical door thicknesses, but thicker doors require longer screws to achieve full thread engagement and secure hardware mounting. This screw pack is finished to match both US26 Bright Chrome and US26D Satin Chrome finishes, ensuring a clean, consistent appearance on the installed lock. Licensed locksmiths and residential door hardware installers use this pack when retrofitting or installing deadbolts on oversized or custom door assemblies.

This screw pack is intended for use with Kwikset 660 single cylinder and 870 double cylinder deadbolt series installed on thick door configurations. It is suited for residential entry door applications where standard-length screws fall short of the required engagement depth. Both US26 Bright Chrome and US26D Satin Chrome finish variants of those deadbolt models are supported. The pack is sold as a single unit and is a direct OEM accessory from Kwikset for maintaining finish consistency and structural integrity of the lock installation.

Installation Notes

Installation should be performed by a qualified locksmith or experienced door hardware installer. Before replacing or installing screws, ensure the door is stationary and the existing lock hardware is fully removed from the door prep. Use a properly sized screwdriver or driver bit to avoid stripping fastener heads. Verify door thickness falls within the intended range for this screw pack before installation.
