T45 Torx
1 in Driver Bit
Keep a T45 Torx replacement ready for repeat fastening, and match the bit format to your tool setup.
Product Overview
Match the T45 Torx tip to the screw recess; screw diameter alone does not identify the bit.
The 1 in length helps you plan access to the screw; allow space for the tool nose as well.

Choose the Correct Fit
Match the T45 Torx tip to the screw recess. Clean out paint, dirt or metal chips so the bit can seat fully.
Fit this insert bit into a holder with matching shank and retention. Check that it is secure before operating the tool.
Installation & Care
Allow room for the 1 in bit and the tool nose. Start slowly, then use only the force needed to seat the fastener.
Inspect the tip between tasks. Replace a rounded, cracked or twisted bit; increasing pressure will not restore its fit.

Important Product Questions
Can I substitute another tip profile?
Choose the specified Torx profile and T45 size. A different recess shape or a nearby size may appear to engage but can slip and damage the screw.
What if the bit slips under load?
Stop and check the screw recess, tip condition and tool alignment. A damaged recess or wrong fit can cause slipping; forcing it may make removal harder.
Does impact duty set the screw torque?
No. Follow the torque requirement for the fastener and assembly. An impact-rated bit does not limit torque or prevent damage from overtightening.
