1/4-28 x 3/4 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is specified where a tapered conical point should nest into a prepared shaft spot while the nylon insert adds prevailing torque. The cone point is selected for mechanical interlock because the tapered tip seats into a spot or dimple instead of only pressing on the surface. Use this alloy steel body with the nylon locking pellet where the drawing calls for a mechanical set screw, not a corrosion-focused stainless part.
Robotics end-of-arm tooling and small fixtures may use the headless form where a protruding screw head would interfere. Plain alloy steel is not selected for corrosion resistance, so keep parts oiled or choose a stainless request when the environment requires it.
Cold Headers can discuss pelletized set screw needs when a print requires prevailing torque in addition to point engagement. Cold Headers supports distributor, OEM, and MRO sourcing when the item has to be defined by size, point, material, drive, and insert. Confirm size, hex key, point style, and marking tolerance before substitution.
