The fillister head profile offers a taller head height and smaller diameter than a pan head, making it a practical choice in counterbored applications where a low-profile fastener would lose purchase. At 2.5 inches length under head, this screw provides solid thread engagement in thicker material stacks. The slotted drive is compatible with standard flat-blade screwdrivers, making it accessible in field and shop environments. Finished in zinc for corrosion resistance, the screw is manufactured to ASME B18.6.3 and SAE J82 standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for mechanical assemblies, electrical enclosures, HVAC equipment panels, and general trade applications where a coarse-thread 1\/4-20 inch fastener with a fillister head is specified. It is commonly installed by HVAC technicians, electricians, plumbers, and industrial maintenance personnel. The 2.5-inch length under head accommodates moderate material thickness without protruding excessively on through-bolt installations. These screws are sold individually as a package of one unit, with a minimum order quantity of 50 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 coarse thread for broad tool and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003eFillister head profile suits counterbored holes and confined clearance areas\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion protection for interior and light-duty exterior use\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction with Grade J82 material specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for equipment and assemblies that specify a 1\/4-20 x 2.5-inch fillister head slotted machine screw per ASME B18.6.3 or SAE J82.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with an appropriately sized flat-blade screwdriver to avoid cam-out and slot damage.
