4-40 x 1/4 combines an alloy steel socket set screw body with a nylon tip for applications where the contact surface matters as much as the thread and length.
Typical uses include robotics joints on finished shafts, compact pivots, and controlled-contact positioning details. The alloy body is the dry-service workhorse choice when the bill of material calls for an alloy socket set screw with a soft face. 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 thread locking rather than surface protection, Alloy Set Screws with Nylon Insert solve a different job than nylon or brass tip screws.
