Kwikset 81248-003 Thick Door Chassis Screws

Product Description

The KWIKSET 81248-003 is a thick door chassis screw set designed to secure door lockset hardware on oversized or thick door applications. These screws provide the mechanical fastening needed to properly mount chassis components when standard-length fasteners fall short. At 3.5 inches in length, they accommodate doors that exceed standard thickness tolerances. Available in US11P Venetian Bronze and 514 Matte Black finishes, the hardware blends with matching Kwikset lockset trim. Installation is handled by locksmiths, residential carpenters, and door hardware technicians during lockset installation or replacement.

These chassis screws are suited for residential door hardware installations where thick door construction requires extended fasteners. They are commonly used when retrofitting or installing locksets on solid-core doors, oversized entry doors, or doors with added weatherstripping buildup that increases overall thickness. The dual-finish availability makes them appropriate for matching existing Kwikset hardware in Venetian Bronze or Matte Black trim packages.

Compatibility

Designed as an OEM-style replacement chassis screw for Kwikset lockset hardware requiring thick door fastener solutions in US11P Venetian Bronze or 514 Matte Black finish.

Installation Notes

Installation is performed by locksmiths or door hardware technicians during lockset mounting or replacement. Remove all tension from the door latch and ensure the door is in the open position before disassembling the chassis. Use a properly sized screwdriver to avoid stripping the screw head. Do not overtighten, as excessive torque can crack the chassis housing or door bore finish.
