BSCIOriginChinaHex Key WrenchHex keys, also known as Allen keys or
Allen wrenches, are a vital tool for mechanics, engineers, and
machinists working with hex fasteners. These L-shaped bars allow
torquing bolts, screws, and other fasteners in hard-to-reach spots
and tight quarters where bulky wrenches are unusable. With a
versatile and compact design, hex keys provide efficient access and
usability across limitless applications.What is a Hex Key?Hex keys
consist of a short L-shaped metal bar with a hexagonal shaft on the
long arm that engages with hexagonal socket screws and bolts. The
short arm provides improved leverage and access for generating
torsion and driving the fastener. The most common size range is
from .028" across flats up to 3/8", covering imperial and metric
fasteners. Long-arm versions give even greater reach.Main Fastener
