KSP spline spike lug nuts are designed for OE Toyota-style wheels and compatible applications that use M14 x 1.5 wheel studs with a mag/flat seat. This 24-piece set is built for a secure, flush fit on deeper truck-style lug pockets, making it suitable for Toyota Tacoma, Tundra, 4Runner and select Lexus applications when the vehicle thread size and wheel seat type match. Each lug nut features a precision flange design that helps distribute clamping force evenly across the wheel mounting surface. The one-piece construction is made from AISI 1035 carbon steel and heat-treated to Grade 8 strength for durable daily driving and truck use. CNC-machined threading supports smooth installation and proper engagement with matching studs. The silver chrome-based finish adds a clean spike-style appearance while helping resist wear and corrosion; the finish is tested with a 72-hour salt spray process. Dimensions include approximately 1.4 in width and 4.3 in total length. A matching socket is included for installation. Always verify your vehicle year, model, wheel type, thread pitch and seat style before purchase, especially when using OE wheels or TRD factory wheel setups.
