For exact-size replacement work, 1/4-20 x 1 identifies the thread, threaded body length, and nylon tip material in a single set screw listing.
Typical uses include packaging changeover points, adjustable guide rails, and repeatable machine settings. That makes it useful when the set screw must bear on a finished or plated part and later be adjusted again. Nylon is the softer contact choice for delicate finishes and repeated adjustment.
Cold Headers brings decades of socket fastener experience to tipped screws used in maintenance, production, and repair work. For maximum bite instead of surface protection, the related cup point alloy set screw family is the better comparison.
