RAYS 17HEX L31 Black Lug Nut & Lock Set | M12 x 1.5 (AE86 Corolla / AW11 MR2 / AE92 Corolla)

RAYS 17HEX L31 Black Lug Nut & Lock Set – M12 x 1.5

For 1983–1987 Toyota Corolla AE86, 1984–1989 Toyota MR2 AW11, and 1987–1991 Toyota Corolla AE92 coupe equipped with M12 × 1.5 right-hand studs and aftermarket 60° conical-seat wheels.

Overview

The RAYS 17HEX L31 Black Lug Nut & Lock Set is a 20-piece wheel-hardware set for the 1983–1987 Toyota Corolla AE86, 1984–1989 MR2 AW11 and 1987–1991 Corolla AE92 coupe applications. Fitment depends on M12 × 1.5 right-hand studs, aftermarket 60° conical wheel seats, adequate thread engagement and nut/adapter clearance, not the chassis name alone.

This black 20-piece set includes 16 standard lug nuts and four locking lug nuts, along with the required lock-key and long socket adapters. The standard lug nuts measure 31 mm in overall length and are manufactured from SWCH10R steel.

Corolla AE86, MR2 AW11 and Corolla AE92 coupe applications use a four-lug configuration. Installation uses 12 standard lug nuts and four locking nuts, leaving four standard lug nuts as spares.

Key Features

• M12 x 1.5 thread pitch for Toyota Corolla AE86, MR2 AW11 and Corolla AE92 wheel studs
• Designed for aftermarket wheels with 60° conical lug-nut seats
• Compact 17HEX design for aftermarket wheel lug openings
• SWCH10R steel construction
• Black finish
• 31 mm standard lug-nut length
• Approximately 48 g per standard lug nut
• Includes 16 standard lug nuts and four locking lug nuts
• Includes lock-key and long socket adapters
• Provides one locking lug nut per wheel on four-lug Corolla AE86, MR2 AW11 and Corolla AE92 applications

Four-Lug Set Configuration

This RAYS set contains 20 wheel nuts because it is packaged as a five-hole wheel set. Toyota Corolla AE86 Trueno / Levin / GT-S / SR5, Toyota MR2 AW11 and Corolla AE92 applications use four wheel studs per wheel and therefore require 16 installed wheel nuts.

Using one locking nut at each wheel requires:

• 12 standard RAYS lug nuts
• 4 RAYS locking lug nuts
• 4 remaining standard lug nuts kept as spares

The additional standard nuts do not affect installation. Fitment is determined by the M12 x 1.5 stud thread, tapered wheel-seat design, and available lug-hole clearance of the aftermarket wheel.

Fitment Notes

• For aftermarket wheels with a matching 60° conical seat and M12 × 1.5 right-hand studs only. This is not blanket original-wheel fitment.
• Excludes flat/washer, mag/shank, ball/radius, inverted and other nonmatching seats or changed stud threads.
• The nut seat must contact the wheel fully, with adequate thread engagement and clearance for the nut and supplied adapter. Spacers, changed studs or hub conversions can alter these requirements.
• Closed-end nuts require sufficient internal stud clearance; the stud must not bottom out before the wheel is clamped.
• The adapter outside diameter is 24 mm; the wheel recess must provide clearance.
• AE86, AW11 and AE92 four-lug applications use 12 standard nuts and four locks, leaving four standard nuts as spares.

Which Lug Nut Set Should You Buy?

Project Kics R40 — Best for extended studs and less rubbing against the wheel seat

Choose R40 if you need room for extended studs or want less rotational rubbing against the wheel seat: its open end leaves no cap for the stud to bottom against, while the floating taper collar stays seated as the nut turns. The 44 mm body has an open end rather than a cap; the wheel seat must support the full collar, and this set includes separate locking nuts.

RAYS L31 — Best for a shorter, understated look with separate wheel locks

Choose RAYS L31 if you want a more compact, closed-end appearance with conventional hex nuts and separate wheel locks. Its 31 mm standard nuts are shorter than the other two choices, but the closed ends require enough internal room for your studs; the locks use their own key.

Project Kics Kyokugen — Best for a taller, capped look with matching nut profiles

Choose Kyokugen if you prefer a taller closed-end appearance and the same seven-sided profile on every nut. The 42 mm nuts require the supplied heptagon adapter for every wheel nut; this is not a separate locking-nut system, and the closed ends still need adequate internal stud clearance.

All three require M12 × 1.5 right-hand studs, matching aftermarket 60° conical wheel seats, adequate thread engagement and room for the nuts and their tools. Overall nut length is not usable internal stud clearance.

Our Recommendation: Choose RAYS L31 for a compact capped appearance with separate locks, R40 when extended-stud clearance or reduced wheel-seat rubbing matters more, or Kyokugen for a taller capped look if you are comfortable relying on its dedicated adapter. The best choice is the one that clears your actual wheels and studs.
