1/4 Hex Insert Bits 25 mm Long

When one hex size does most of the work, replacing a full set every time that size wears out wastes money and drawer space. This 3-pack from Teng Tools solves the problem by delivering three identical metric insert bits in the single size you actually need.

Each bit measures 25 mm (approximately 1.0 in) in overall length and accepts any standard 1/4 inch hex holder, quick-change chuck, or compatible driver. The short profile keeps the tool compact, which pays off in confined spaces where clearance is limited and a long shank would force you to work at awkward angles.

Metric sizing ensures a precise match to the corresponding hex recess, reducing the risk of cam-out and fastener damage. Whether you are seating cap screws on machinery, tightening set screws in pulleys, or driving socket-head fasteners during an HVAC install, a correctly sized bit protects both the fastener and the workpiece.

The 3-pack format lets you distribute spares across your primary tool bag, your service vehicle, and the shop bench so a worn or misplaced bit never stalls a job. Ordering individual sizes also means the rest of your collection stays intact — no need to buy seven sizes to replace one.

Teng Tools designs every hand-tool accessory for professional daily use. Pick the metric size that matches your workload and keep three fresh bits within reach at all times.
