GORILLA Small Diameter Spline Duplex Lug Nuts – 14mm x 1.50 Thread, Black 32‑Piece Set, Dual 13/16" & 7/8" Hex

GORILLA Small Diameter Spline Duplex Lug Nuts are a 32-piece black-finish wheel hardware set engineered for 14mm x 1.50 threaded studs, using a unique spline design and dual 13/16" & 7/8" hex engagement for secure, low-profile fitment.

Designed for vehicles requiring a compact lug nut profile and metric 14mm x 1.50 thread pitch, this K8TS-14150BGR set delivers an OEM-style look with aftermarket durability. The duplex spline form provides strong torque transfer across the lug face while the two hex socket sizes let you use common sockets or tools for installation and removal. The black finish offers corrosion resistance and a stealth appearance, making these lug nuts suitable for steel and alloy wheels that accept small-diameter spline nuts.

How do these lug nuts fit different wheel types?

These spline duplex lug nuts are made for wheels that accept small-diameter, spline-style nuts and studs with a 14mm x 1.50 thread. Their reduced outer diameter and spline geometry allow them to seat properly in wheels with smaller openings while maintaining clamping force. Always verify wheel seat type and stud thread before installation.

• Thread size: 14mm x 1.50 (metric).
• Compatible with spline-style taper or flat-seat wheels that accept small-diameter nuts.
• Check wheel center hole clearance and stud length for correct fit.

What tools do I need to install and remove these duplex lug nuts?

The duplex design accepts both 13/16" and 7/8" hex sockets, so you can use a standard socket set or impact socket rated for lug nuts. For best results use a torque wrench to reach the vehicle manufacturer’s specified torque. Avoid shallow or damaged sockets that could round the spline or hex faces.

• 13/16" or 7/8" hex sockets for hand or impact tools.
• Torque wrench for final tightening to OEM torque specs.
• Clean sockets and correct-size deep sockets reduce slippage risk.

What performance and protection does the black finish provide?

The black coating on these lug nuts acts as a barrier against moisture and road contaminants while giving a low-profile aesthetic. It resists mild corrosion and helps maintain appearance over time, though environmental exposure and harsh chemicals can eventually wear coatings. Regular inspection ensures the finish remains intact and the lug nuts perform safely.

• Matte black finish for subdued visual style.
• Protective coating reduces oxidation compared with bare steel.
• Inspect periodically and replace if coating chips or corrosion appears.

Who is this for: This 32-piece set is aimed at owners of vehicles that require 14mm x 1.50 small-diameter spline lug nuts—commonly light trucks and some passenger cars with aftermarket or OEM spline wheels. It suits DIY mechanics, professional installers, or anyone swapping wheels who wants a compact-profile, dual-hex tool-friendly lug nut. If you need metric thread compatibility, a black finish for stealth looks, and a lug nut designed to fit tighter wheel openings, this GORILLA set offers a complete hardware solution.
