Product Identity

Middle Atlantic HP500 supplies 500 black oxide truss-head screws with factory-installed nylon washers. Each fastener uses 10-32 threads and a self-guiding pilot point. Heat treatment strengthens the steel and resists head stripping. The reusable plastic jar keeps the hardware organised on site.

Target Installer

Rack builders who need a clean, modern finish under trim strips will appreciate the low-profile truss head. Buyers who want more storage or a different thread pitch should look at something else. The kit is sized for standard 3/4 long rack mounting jobs.

Installation Notes

Phillips drive and pilot point let the screws start straight without a separate pilot hole. Nylon washers stay on the shank so nothing drops during overhead work. Over-torquing can still strip the heat-treated heads, so drive slowly near final seating.

Questions about this item

What rack equipment must I already have for these 10-32 truss-head screws to mount correctly?

You need rack rails or equipment with standard 10-32 threaded holes; the self-guiding pilot points on these screws are designed to start easily in those threads.

Will the black oxide finish and included nylon washers protect my existing painted rack rails from scratches?

Yes, the factory-installed nylon washers act as a buffer between the screw head and the rail surface, preventing marring on painted or powder-coated rails.

How can I confirm the heat-treated screws are seating properly without stripping the Phillips drive?

Drive each screw until the truss head sits flush against the washer; the heat-treated steel resists head stripping when the pilot point engages the 10-32 threads cleanly.
