Why Stock This Item

Small hex fasteners appear across industries—electronics assembly, precision machinery, HVAC systems, and automotive electrical work. A 2.5mm bit fills a gap that larger H3 or H4 bits cannot address, making it indispensable for shops serving diverse customer bases. The 1/4-inch shank ensures universal compatibility with modern quick-change systems, eliminating adaptor friction and reducing technician downtime.
