Eklind makes hex keys that work at angles other brands can’t match. Their ball-end design allows hex screws to be tightened or loosened at off-angles up to 30 degrees — the difference between reaching that buried set screw and pulling half your equipment apart.
The 18-piece combo set (model 13218) gives you the full spread of sizes most contractors need daily. Color-coded plastic storage holders: Red for SAE (Standard) and Blue for Metric sizes means no more squinting at size markings when you’re upside down under a furnace.
Ball-End Engineering and Real-World Access
The 30-degree angle isn’t marketing fluff. General workshop maintenance and assembly where angled entry is required. Automotive repair, specifically for accessing bolts in cramped engine compartments — exactly where traditional straight hex keys force you to remove three other components first.
Precision machined for high tolerances to ensure a snug fit in fasteners, preventing rounding. That precision matters when you’re applying serious torque at an angle. Sloppy tolerances mean rounded fasteners, and rounded fasteners mean callbacks.
The long-arm design serves two purposes. Long L-shaped keys provide extra reach for deep-set or recessed fasteners and additional torque leverage. More leverage means less grunt work. More reach means accessing hardware buried behind HVAC plenums or inside equipment panels.

Set Configurations and Professional Organization
Model 13218 packages their two most popular sets together — 13211 and 13607. You get 11 SAE sizes from .050” to 1/4” and 7 metric sizes from 1.5mm to 6mm. That covers 95% of what you’ll encounter in commercial HVAC, electrical panels, and industrial equipment.
Compact plastic holders firmly retain each key in a size-marked hole. The holders actually work — keys stay put bouncing around in a service truck but pull free without fighting them. Keys can be very tight in the holder when brand new, requiring effort to remove, but they break in after a few uses.
The color coding pays off when you’re training apprentices. Hand them the blue holder for metric equipment. Red holder for domestic. No conversion charts, no guessing, no stripped fasteners from jamming the wrong size.
Industrial-Grade Specifications That Matter
8650 chrome nickel alloy steel, which is heat-treated for maximum torque and wear resistance. Not generic “alloy steel” — a specific formulation engineered for hex key applications.
USA manufacturing quality is evident in the steel’s toughness. The ball end is sturdy and doesn’t snap under reasonable pressure. That’s contractors talking, not marketing copy. The ball ends take abuse without shearing off — critical when you’re leaning into a fastener at an awkward angle.
Black oxide finish may wear off with heavy professional use. Fair warning. The coating protects against rust but won’t survive years of daily abuse. For Montana’s humidity swings and temperature extremes, that black oxide coating buys you time but isn’t permanent protection.
Founded in 1923 and based in the United States, the company is known for producing durable tools made from high-quality 8650 chrome nickel alloy steel, which is heat-treated for maximum torque and wear resistance… employing over 100 people in their Illinois factory. Real factory, real employees, real quality control.
Frequently Asked Questions
Q: How do Eklind hex keys compare to cheaper imports? A: Consistently rated 4.5/5 stars across major retail platforms (Amazon, Home Depot, Lowe’s). The Made in USA construction shows in the steel quality and dimensional accuracy. Import keys work until they don’t — usually when you need them most.
Q: What’s the real advantage of ball-end design? A: Access. Electronics and computer hardware repair involving small metric/standard hex screws. HVAC system service and repair. Picture reaching a set screw behind ductwork or inside a control panel. Straight keys need perfect alignment. Ball ends give you 30 degrees of forgiveness.
Q: Which applications benefit most from these sets? A: Machinery and industrial equipment maintenance requiring long-reach tools. Any trade dealing with recessed fasteners — HVAC techs, industrial mechanics, equipment installers. The long arms and ball ends solve access problems that short straight keys can’t touch.
Q: How durable is the black oxide finish? A: Black oxide finish may wear off with heavy professional use. It’s rust protection, not armor. Daily use will wear through it eventually. Store them dry and they’ll last. Leave them in a wet toolbox and you’ll see rust regardless of the coating.
Q: What sizes come in the 18-piece set? A: SAE sizes from .050” to 1/4” (11 keys) and metric from 1.5mm to 6mm (7 keys). Color-coded plastic storage holders: Red for SAE (Standard) and Blue for Metric sizes. Covers standard fastener sizes in HVAC equipment, electrical enclosures, and most industrial machinery.
