Apex 185-9X Hex Screwdriver Insert Bit 1/4 in Drive 7/64 Hex

Product Description

The APEX 185-9X is a hex screwdriver insert bit designed for driving hex fasteners in production, maintenance, and service applications. Built from steel, it accepts a standard 1/4 inch drive and features a 7/64 inch hex tip with a 1 inch overall length. The compact OAL makes it well suited for use in tight spaces where a longer bit would be impractical. This is a solid, no-frills insert bit intended for trade professionals and technicians who need a reliable, properly sized driver for hex cap screws and socket head fasteners in HVAC, electrical, and mechanical service work.

The 185-9X is appropriate for use with any 1/4 inch drive bit holder, impact-rated or standard, in both hand tool and power tool applications. The 7/64 inch hex size corresponds to a Number 6 cap screw, making it a common choice when servicing equipment fastened with small hex socket screws. It is a single-piece insert bit packaged individually, suitable for adding to a tech kit or replacing a worn driver in an existing set.

Key Features

• 7/64 inch hex tip sized for Number 6 cap screws
• 1/4 inch drive shank fits standard bit holders and power tool chucks
• 1 inch overall length suits confined fastener locations
• Steel construction for durability in repeated-use service environments
• No ball end — positive engagement with standard hex sockets

Compatibility

Designed as an OEM-style insert bit for use with any 1/4 inch drive bit holder or power screwdriver accepting standard insert bits.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit ejection. Verify the hex size matches the fastener socket before driving to prevent rounding. Replace bits that show visible wear, rounding, or deformation, as damaged bits increase the risk of fastener damage.
