Flat Head Socket Cap Screw Pack
This 50-piece pack supplies 7/16"-14 x 1.5 inch flat head socket cap screws with a black oxide finish. They suit power and pneumatic accessory tasks where a flush countersunk head is required. The steel fasteners are manufactured by Prospect Fastener under the Kerr Lakeside brand. Builders and mechanics can keep a consistent supply on hand for repeated assemblies.
Upgrade From Mixed or Worn Fasteners
Replacing assorted or corroded screws with this uniform lot eliminates thread mismatch and uneven clamp loads. The jump is worth it when a project demands 50 identical pieces of the same diameter, pitch and length. It also helps when the previous hardware lacked the black oxide coating that reduces glare and adds mild corrosion resistance.
Verify Thread and Countersink Compatibility
Confirm that the mating holes are tapped 7/16"-14 and that the countersink angle matches a flat head profile before ordering. Ensure the 1.5 inch length provides adequate engagement without bottoming out in blind holes. Check that the drive style fits the socket bits available in your workshop.

Questions about this item
What size clearance hole and countersink angle does the 7/16"-14 flat head socket cap screw require?
Drill a 7/16"-14 clearance hole and use a standard flat-head countersink so the head sits flush with the surface.
Which hex key size drives the socket on these 7/16"-14 x 1.5 in screws?
Insert a 3/8 in hex key fully into the socket, apply steady torque, and avoid using a ball-end driver on the final tightening pass.
When should the black oxide finish on these 50 screws be inspected or replaced?
Check for rust or coating wear after exposure to moisture; replace any fastener that shows corrosion or damaged threads.
