ACE Prop Wrench

Every Ace Prop Wrench is CNC-machined to ±0.002” precision and designed specifically for aviation professionals who demand performance without compromise. Unlike competitors’ bulky, corrodible, and imprecise tools, Ace wrenches deliver:

• True 4-Flat Open-End Contact: Our drive-end grips bolts with four precision-machined flats—no rounded throat, no slip. This ensures superior torque transfer, significantly reduced bolt wear, and minimizes “spit-out” under load.

• Slim Head Design for Tight Spaces: Our compact design allows two flats of rotation per engagement—on both the ratcheting-end and the drive end. This provides twice the speed and half the effort of competitors' wrenches. This slim design is made possible by using premium materials versus our competitors' 4140 or 4340 steel.

• Ratcheting Speed-End: The ratchet end is engineered for fast, low-effort, efficient spin with a slimmer profile than any competitor. It’s not just faster—it’s smarter.

• Laser-Etched QR Code: Every wrench includes a permanent QR code, quickly linking to our torque calculator with diagrams and instructions. No guesswork and no paper inserts with links that would soon be lost or unreadable.

• Designed as a True Crowfoot Adapter: Unlike others, we acknowledge the torque implications of offset wrenches. Our calculator helps you adjust torque values precisely—no vague advice, no risky assumptions or omissions.

Premium Grade 5 Titanium. Non-magnetic. Corrosion-proof. Built for life.

• Material: CNC’d from aerospace-grade Grade 5 Titanium. Immune to corrosion—even in saltwater environments. Doesn't have or require coatings and isn't laser-cut like other cheap wrenches in the market.

• Magnetic Safety: Prevents stray magnetic charges from being transferred to unintended locations.

• Weight/Durability: Titanium offers unmatched strength-to-weight ratio and longevity. It weighs approximately 1/2 that of steel wrenches. This results in faster, less strenuous work.

• Finish: Raw titanium with laser markings for clarity and permanence. No coatings, no compromises. This is the last prop wrench you'll buy--pass it on to your heirs.

This is the ultimate prop wrench—engineered for professionals who refuse to settle.

15-5PH H900 Stainless Steel possesses extreme strength and is highly corrosion resistant. Built for relentless use.

• Material: CNC’d from hardened 15-5PH H900 Stainless Steel. 2x-3x stronger compared to competitors' 4130 or 4340 steel wrenches.

• Corrosion Resistance: Far superior to black oxide-coated steel wrenches. No flaking, no rust.

• Strength: Designed for high-torque applications with minimal wear on bolts and fittings.

• Finish: Brushed stainless with laser markings and QR code for torque calculator access.

This is the wrench for those who demand strength, precision, and reliability—without the titanium price tag.
