Minerallac 39015D – Frequently Asked Questions
1) Will the Minerallac 39015D driver bit fit the hex head screws on an electrical enclosure?
The Minerallac 39015D is a 5/16 inch hex tek driver bit sized for #10-12 hex washer head screws, the range used on panel and enclosure assembly, strut, and sheet metal work. If the screw head across the flats measures 5/16 inch, this bit seats it. For 1/4 inch hex heads (common on smaller #8 tek screws) you need a 1/4 inch driver instead.
2) Does this hex driver bit hold the screw on its own so I can start fasteners one-handed overhead?
Yes. The 39015D has a magnetic socket, so a #10 or #12 hex head screw stays seated in the bit while you position it. That matters on overhead HVAC hangers and panel lids where you cannot get a second hand on the fastener. It is magnetic retention, not a spring-loaded holder, so a heavy long screw can still tip if you bump it.
3) I am stocking driver bits for a maintenance shop. Is one 5/16 bit enough for all our tek screws?
No. The 39015D covers the 5/16 inch hex head size used on #10 and #12 screws. Self-drilling and sheet metal screws in the smaller sizes typically take a 1/4 inch hex driver, and larger structural tek screws go up to 3/8 inch. Stock 1/4, 5/16, and 3/8 together if your crews work across panel, strut, and roof deck fastening.
4) Can I run this bit in an impact driver or a cordless drill?
The 39015D mounts in a hex driver or a power tool chuck, so a drill chuck or a quick-change hex holder both work. Drive it at the moderate speed self-drilling tek screws want; running flat out burns the screw point before it bites sheet metal.
5) What is this bit made of, and does it hold up to daily tek screw driving?
Steel construction, made in Taiwan. The socket is a hex tek design, which engages the full flats of the screw head rather than a cross recess, so there is no cam-out to chew the bit. Magnetic sockets do pick up swarf from self-drilling screws, so blow the socket clean periodically to keep the head seating fully.
