Allen wrench sets

Introduced over a century ago by William J Allen in 1909, the hex or Allen wrench set was an ahead-of-time invention whose popularity grew quickly. Its widespread uses are appreciated from homes to industrial settings. The set is essential in professional duties, workshops, and home DIY projects such as installing door handlebars, repairing chairs, and tightening toilet paper holders. 

Unlike flat-headed screws commonly known as Phillips, which can be tightened or loosened by a screwdriver that is slightly smaller or larger than the screw, Allen fasteners require the exact Allen key- you can’t simply gamble around with any key. Therefore, having a full set of these irreplaceable tools is crucial. While there are different types of Allen wrench sets, this guide seeks to explore the top five best sets.  Our recommendations are based on the latest customer sentiment data and recommendations from our community of metallurgists:

1. LEXIVON Master Wrench Key Set

LEXIVON Master Wrench Key Set, 35-Piece Long Arm Ball End Hex Keys | 3-Pack Metric/SAE & Star, Industrial Grade S2 Alloy Steel (LX-131)

LEXIVON is one of the leading manufacturers of fastening tools. It uses cutting-edge technology to manufacture keys from special metal bars and frames. It is precisely machined with superior heat-treated S2 steel alloys. These are shock-resistant ductile steel bars that outperform regular carbon steel. Able to work under stressful conditions, the key set will maintain its shape offering more turning power. 

Most steel parts are prone to rust, however much they are protected, but this is not the case with LEXIVON. The set is protected using a manganese phosphate compound against corrosion from common garage fluids and chemicals. Reports also indicate industrial manganese phosphate is a rust-proof compound that, once applied, doesn’t come off the protected metal easily.

The smooth chamfered edge around right angles and ball end design is not only soft on the hands but also allow a 25-degree reentry angle. This means you have a wide angle to fit the key into the fastener. 

When manufacturing the master wrench set, the company contracts various subsidiaries, especially from Taiwan. As you might know, Taiwanese companies merge robotics and human knowledge to come up with decent high-quality tools. 

Lastly, the company sells the master key sets in 10, 32, and 35 pieces. The latter is a complete set of 11 inches long hex keys with extra Torx keys. If you have difficulties differentiating almost identical tools from a set, LEXIVON laser-etched tools are easy to identify and organize in a case.

2. Amazon Basics Hex Key Allen Wrench Set

Amazon Basics Hex Key Allen Wrench Set with Ball End - Set of 26

Amazon basics Allen wrench set is a collection of durable 26 pieces of keys in standard and metric sizes. It is unclear why the company landed on 26 pieces, but customers are okay with the number. One customer in the review section even commended the set had what exactly they needed to put together a desk whose manufacturer discontinued the provision of assembling tools. 

Made of chrome vanadium steel, the metal boasts rugged strength. To achieve that, chrome-vanadium steel alloys are mixed with carbon, manganese, silicon, and of course, chrome and vanadium. The last two elements ensure that each key is hard and resistant to corrosion and rusting. 

For beauty and ease of use, manufacturers sandblast each piece before coating it with a thin layer of black oxide finish. Black oxide’s unique formulation of water, oil, and sulfur salts also maintains the shape of the key and reduces friction when in use. 

The 8.2 inches long arms provide an extended reach and leverage torque into your hands. At one end of the keys, corners are beveled for easy insertion. The other end features a ball-end design with a wide entry angle of up to 25 degrees.

Buying Guide for Allen Wrench Sets


The primary and coating material for a tool affects its durability, appearance, and strength. Select Allen keys made from steel alloys such as S2 or vanadium steel and coated with black oxides and rust-proof compounds. They are long-lasting, smooth on the hands, and stunning.


Allen keys are sold in sets, and they should fit perfectly in the hex nut you are going to work on. Thus, check for the key’s sizes before buying an entire set. 

Storage cases 

A set of hex wrenches has over ten keys. If you don’t have a good storage case, you might lose some of these keys. Fortunately, most manufacturers provide storage cases for each set. In fact, cases have slots to ensure all keys fit in perfectly. 

Another advantage is slots help you identify missing keys on time. You can either look for them around the workstation or plan on how to replace them to avoid future inconveniences. 

From customer reviews, box-like cases were highly rated. Go for products like MulWark wrench sets which have box-like storage cases. 

Sizing criteria 

Most tools use SAE and metrics sizing criteria. For starters, SAE uses inches is common in countries affiliated with America, while metrics are used by the UK and Australia.
