Muteki SR48 Open End Lug Nuts | 12x1.50 Thread Pitch | 48mm Length | Satin Silver | 20-Piece Set

The Muteki SR48 Open End Lug Nuts in 12x1.50 thread pitch, 48mm length, and satin silver finish are one of the most popular and widely recognized JDM lug nut sets in the enthusiast market — a clean, purposeful lug nut design that has become a staple of the JDM wheel fitment scene. The SR48's open-end design accommodates extended wheel studs, lug bolts, and wheel spacer applications where a closed-end lug nut would bottom out before achieving correct clamping force. Muteki (by Wheel Mate) is one of the most respected JDM wheel accessory brands in the North American market — known for their SR48 and SR35 lug nut lines that combine correct engineering with the clean aesthetic that JDM enthusiasts demand.

Key Features:

• SR48 open-end design — Muteki's SR48 open-end lug nut — the open end allows the lug nut to be used with extended wheel studs, extended lug bolts, and wheel spacer applications where a closed-end nut would bottom out before achieving correct clamping force
• 12x1.50 thread pitch — 12mm diameter, 1.50mm thread pitch — one of the most common thread pitches in the Japanese performance market — correct for a wide range of Toyota, Honda, Mazda, Subaru, and Mitsubishi applications
• 48mm length — 48mm overall length — the SR48's longer length provides more thread engagement than shorter lug nuts — correct for standard and extended stud applications
• Satin silver finish — Muteki's satin silver finish — a clean, understated finish that complements a wide range of wheel colours and finishes
• 20-piece set — 20 lug nuts per set — correct for a 5-lug vehicle (4 wheels x 5 lugs = 20 lug nuts)
• Hex size — verify the correct hex socket size for the SR48 before installation — Muteki SR48 lug nuts use a specific hex size that may differ from factory lug nuts
• Muteki / Wheel Mate quality — manufactured by Wheel Mate, one of the most respected JDM wheel accessory brands in the North American market

Open-End Design — Why It Matters:

The Muteki SR48's open-end design is a key feature for enthusiast wheel fitment applications. A closed-end lug nut has a cap that limits how far the lug nut can travel down the stud — if the stud extends beyond the closed end, the nut will bottom out on the stud before achieving correct clamping force on the wheel. This is a common issue with wheel spacers (which use longer studs or extended lug bolts), aftermarket wheels with different hub depths, or any application where the stud protrudes further than the factory configuration. The SR48's open end eliminates this limitation — the lug nut can travel as far down the stud as required to achieve correct clamping force, regardless of stud length.

12x1.50 — Common Applications:

The 12x1.50 thread pitch is one of the most common lug nut thread pitches in the Japanese performance market — used across a wide range of Toyota, Honda, Mazda, Subaru, and Mitsubishi vehicles. Verify your specific vehicle's lug nut thread pitch before ordering — common Japanese thread pitches include 12x1.25 and 12x1.50, and using the incorrect pitch will damage the wheel studs and lug nuts.

Specifications:

Fitment Information:

• 12x1.50 thread pitch — compatible with any vehicle using 12x1.50 lug nut thread pitch
• Common 12x1.50 applications: Toyota (most models), Honda (most models), Mazda (most models), Subaru (most models), Mitsubishi (most models) — verify your specific vehicle's thread pitch before ordering
• Note: Verify your vehicle's lug nut thread pitch (12x1.25 vs. 12x1.50) before ordering — using the incorrect thread pitch will damage wheel studs and lug nuts. Verify the correct conical seat angle for your wheels — most aftermarket wheels use a 60° conical seat. Verify the correct hex socket size for the SR48 before installation. 20-piece set — correct for a 5-lug vehicle.

What's Included:

• 20x Muteki SR48 open-end lug nuts — 12x1.50 — 48mm — satin silver (WHM32906SS)
• Muteki lug nut key/socket — refer to Wheel Mate's product documentation to confirm if a key is included

Installation Notes:

• Verify correct thread pitch engagement before torquing — the lug nut should thread on smoothly by hand for the first several turns — if resistance is felt immediately, stop and verify thread pitch compatibility
• Torque lug nuts to your vehicle manufacturer's specified torque value — do not use an impact wrench without a torque stick — over-torquing can damage the wheel's lug seat and the lug nut
• Use the correct hex socket size for the SR48 — using an incorrect socket size can round the lug nut's hex
• Re-torque lug nuts after the first 50-100km of driving — thermal cycling can cause lug hardware to settle after initial installation
• Inspect lug nuts for thread wear or damage before each reinstallation — replace any lug nut that shows signs of thread damage or deformation
