13-piece hex L-wrench set

This Bondhus 116-12137 set contains 13 long-arm hex L-wrenches sized from .050 to 3/8 inches. It is built for mechanics and technicians who need deep reach into recessed fasteners. The precision-cut tips ensure full engagement with socket heads to reduce rounding. Made in the USA, the tools suit professional maintenance and assembly tasks.

Black oxide finish and long-arm leverage

The black oxide coating resists corrosion during daily shop use without adding thickness that affects fit. Long arms deliver extra torque leverage so stubborn screws turn with less applied force. Precision machining keeps tip geometry consistent across every size. The set handles general fastening work where extended reach is an advantage.

13 sizes cover .050 to 3/8 inch

The range includes .050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16 and 3/8 inch keys. Buyers needing metric sizes or shorter arms for tight clearances will not find them here. The imperial-only selection fits SAE hardware common in North American equipment. Verify the exact sizes required before purchase.

Questions about this item

How do I keep the 13 long-arm hex L-wrenches from rolling off the bench during use?

Store each size in the labelled slot of the supplied holder; the tight fit stops the 13 pieces from sliding out when the tray is tilted.

What wear appears first on the black-oxide finish after repeated fastening cycles?

The coating thins at the precision-cut tips first, exposing the underlying alloy steel on the smallest sizes such as .050 and 1/16 inch.

At what point does the long arm become a disadvantage when torquing a stubborn 3/8-inch fastener?

The extra leverage can twist the 3/8-inch wrench if the fastener seizes; switch to a shorter driver or impact socket once resistance spikes.
