Weighing less than 5 lbs, the PT-7421 Air Operated Spin Pull to Pressure Nutsetter has evolved from the production tested reliable stroke adjustable version, the 7420.  With pull force adjustment capability the PT-7421 allows the user to insure that the force imparted to the fastener will not exceed the bearing strength of the material it is being installed into (ie. fiberglass, wood, composites) or the thread of the fastener itself.  This feature significantly reduces the potential for damage or excessive wear to the pull up stud (mandrel) and anvil assembly due to material thickness variations.  Affording a .275" stroke, the PT-7421 is capable of installing virtually all blind nut and insters within its capacity range in one stroke, including Rivnuts® (NAS1329, NAS1330, MS27130), Plusnuts®, AVK ribbed inserts and Blind Nuts, AVdel Nutserts and Thin Sheet Nutserts® (TSN).  Importantly, if the user inadvertently recycles the riveter after installation, the fastener threads and/or parent material remain unaffected.  Utilizing standard Grade 8 Socket Head Cap Screws as pull up studs (mandrels) reduces replacement cost and permits wide flexibility for adapting to different fastener lengths.  The driving anvil assembly is adjustable to permit quick adaption to most all standard blind rivet nuts or inserts.
