Constructed from high-strength carbon steel with a thick black powder coat and stainless-steel hardware, the spring base resists rust and deformation while allowing the whip or antenna to flex under force instead of snapping. The set includes one spring base, one stainless nut and two washers and installs quickly using an M12*30 threaded screw through a 0.47\" hole in your vehicle or bracket.\u003c\/p\u003e\n\n\u003ch3\u003eWill this mount fit my existing whip light or antenna?\u003c\/h3\u003e\n\u003cp\u003eThe mount is made for shafts that use screws with a minimum diameter of 0.448\" and a maximum of 0.465\" and fits non-spring base models only. Confirm the screw diameter and that your current mounting hole is roughly 0.47\" before ordering. If dimensions match, the M12*30 threaded base secures through standard brackets on many vehicles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible screw diameter: 0.448\"–0.465\"\u003c\/li\u003e\n  \u003cli\u003eRequired vehicle\/bracket hole: ~0.47\"\u003c\/li\u003e\n  \u003cli\u003eThread size for mounting: M12*30\u003c\/li\u003e\n  \u003cli\u003eNot compatible with existing spring-base whip models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the spring design protect my whip light or antenna?\u003c\/h3\u003e\n\u003cp\u003eThe spring element lets the whip or antenna bend and rebound when it hits low branches, tunnel ceilings, or strong gusts. That flexible motion spreads impact energy across the assembly instead of concentrating it at a brittle joint, reducing the chance of breakage.
