Holex Hexagon Key L-Wrench Long | Inch Allen Wrench, Nickel-Plated Chrome Vanadium Steel, 18 Sizes 1/16 to 1 in

Built for fasteners that sit deep in counterbores and recessed assemblies, the Holex Hexagon Key L-Wrench Long is an inch-size allen wrench with extended reach over a standard hex key. The extra shank length turns socket-head screws that shorter keys cannot touch, in machine setups, equipment maintenance, and mechanical assembly work.
Pick the size from the selector, which lists all eighteen of them, from 1/16 in. up to a full 1 in. across flats. Each size is its own item, so you order the single long allen wrench a job calls for, replace one that has worn, or add an odd size without paying for the range a second time. Keeping doubles of the sizes your machines use most is a practical way to outfit a tool crib.

Key features:
• Chrome vanadium steel, through hardened: a toughened key that holds its hex form in daily use
• Nickel-plated finish: uniform protective plating on every key
• Squared and chamfered tips: each one starts into the socket easily and seats fully
• Angled shank: L-form geometry gives two working ends in one key

When does a long hex key beat a standard one?
Long allen wrenches reach fasteners recessed beyond a standard key's depth and add leverage on stubborn screws, which suits machine work and equipment repair.
Applications: machine tool setup, fixture and vise mounting, equipment maintenance, mechanical assembly, machinery installation, repair of inch-fastened equipment.
Industries: industrial maintenance, machinery building, metal fabrication, automotive repair, precision machining, general manufacturing.
Users: machinists, maintenance technicians, mechanics, assemblers, maintenance, repair, and operations (MRO) staff.

What does a long allen wrench drive, and what else is it called?
An allen wrench is an L-shaped hexagonal key for fasteners whose drive is an internal hex socket, socket-head cap screws and setscrews among them. Catalogs also list the tool as a hex wrench, a hex driver, or an l wrench, all named for the bent shape. This Holex pattern is the long version in inch sizing for inch-dimensioned socket screws.

How do you remove a stripped allen wrench screw?
Press a fresh key of the exact size fully into the socket, apply firm downward pressure, and turn slowly. If the socket is already rounded, shop options include a screw extractor, a slightly oversize key tapped in for grip, or cutting a slot for a flat blade. Worn keys cause most stripped sockets, so retire rounded keys early. The squared and chamfered end faces on this key help it seat fully before you apply torque.

Do inch hex keys differ from metric allen key sizes?
Yes. Inch hex keys are dimensioned in fractions such as 5/32 in. and 3/16 in., while a metric allen key comes in millimeter steps. The two do not interchange, since a near-match will rock in the socket and round it. Match the key standard to the fastener standard. This Holex range covers the inch side with 18 sizes, the smallest 1/16 in. and the largest a full 1 in.
