This long exhaust nut features a through-hole for threading safety wire (tech wire), which is required by most sanctioning bodies including SKUSA and USPKS to prevent the exhaust from loosening during competition. \u003c\/p\u003e\n\u003cp\u003eThe exhaust studs on the KA100 cylinder accept two exhaust nuts, one on each side of the header flange. These nuts are torqued to spec and then safety-wired together through the drilled holes. Exhaust nuts should be inspected at every race event for thread damage, loosening, or corrosion from exhaust heat. Replace any nut that does not torque smoothly or shows signs of heat-related weakening.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 nut (order 2 per exhaust header)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTech wire on the exhaust nuts is mandatory in most sanctioned KA100 classes.
