The slotted drive accepts a standard flat-blade screwdriver, making it a practical choice for maintenance and assembly work. Constructed from steel with a zinc-plated finish, this fastener resists corrosion in light-duty environments. It meets ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and material grade compliance. Length is measured under the head at 3.5 inches. This fastener is used by HVAC technicians, plumbers, electricians, and general maintenance professionals wherever a reliable 1\/4-20 threaded fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for residential and light commercial equipment assembly, panel mounting, enclosure fabrication, and component attachment. Pan head geometry provides a low-profile bearing surface across a wide range of materials. The slotted drive style is well established in legacy equipment and panel-box hardware, making it a common replacement option in the field. No washer is included or required under the head per standard specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread size with 3.5-inch length measured under the head\u003c\/li\u003e\n  \u003cli\u003ePan head profile with slotted drive for flat-blade screwdriver installation\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eGrade J82 material designation ensures consistent mechanical properties\u003c\/li\u003e\n  \u003cli\u003eInch system of measurement; no washer included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 threaded machine screw suitable for general mechanical and equipment assembly applications requiring a pan head, slotted-drive fastener to ASME B18.6.3 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using an appropriately sized flat-blade screwdriver.
