SCREW1224-50 is a 50-piece package of 12-24 rack mounting screws with factory-installed nylon washers, supplied in a plastic jar with a screw lid. It is intended for IT and network installers, AV integrators, electricians and facilities teams who mount equipment to 12-24 tapped rack rails in rack cabinets, wall-mount cabinets and open frame racks.

Each screw is a Quadrex truss head fastener made from 1022 low carbon steel with a black oxide finish, heat treated to ANSI B18.6.3 specification. The Quadrex combination recess accepts both Phillips and Robertson (square) drivers, so technicians can work with either tool. A self-guiding pilot point on the tip helps align equipment and start threads, reducing cross-threading and speeding up installation.

The captive black nylon 6/6 washer, 0.429"-0.439" outside diameter and 0.030"-0.040" thick, helps protect painted rack rails and equipment faceplates from scratching as the screw is tightened. The screw itself has a 12-24 UNC-2A thread, an overall length of 0.720"-0.750", a head diameter of 0.425"-0.448" and a head height of 0.103"-0.118".

These screws are manufactured to fit Hammond rack systems and most industry-standard rack rails, making SCREW1224-50 useful for new rack builds, equipment upgrades, ongoing maintenance and replacing lost or damaged rack screws. The part is RoHS and REACH compliant, USMCA compliant and TAA compliant, with a shipping weight of 0.51 lbs (0.23 kg).

Ideal For

  • Installing servers, switches and storage equipment
  • Mounting patch panels, PDUs and UPS systems
  • Data center, colocation and telecommunications cabinets

Frequently Asked Questions

How many screws come in SCREW1224-50?▾

The package contains 50 screws with nylon washers already installed, supplied in a plastic jar with a screw lid.

What thread size are these screws?▾

They use a 12-24 UNC-2A thread, which matches 12-24 tapped rack rails.

What screwdriver do I need?▾

The head uses a #2 Phillips square recess Quadrex combination drive, so it accepts either a Phillips or a Robertson (square) screwdriver.

Do the washers come attached?▾

Yes. Each screw has a factory-installed black nylon 6/6 washer with a 0.429"-0.439" outside diameter to help protect painted rack rails and equipment faceplates during installation.

What is the screw made of and how is it finished?▾

The screw is 1022 low carbon steel with a black oxide finish and is heat treated to ANSI B18.6.3 specification.

Are these screws suitable for square-hole rack rails?▾

For square-hole rails, cage nuts (CAGNUT Series) or a complete mounting hardware kit are the better choice; for round-hole rails, clip nuts (CLIP Series) or CLPKIT screw and clip nut kits are suggested.
