This fastener measures 1 inch in length under the head and is built to ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and material grade compliance. The zinc plating provides baseline corrosion resistance suitable for general indoor mechanical and electrical applications. Electricians, HVAC technicians, plumbers, and general tradespeople use this style of fastener for panel assembly, equipment mounting, and component attachment where a low-profile pan head and simple slotted drive are appropriate.\u003c\/p\u003e\u003cp\u003eThis screw is suited for light to medium-duty fastening tasks in residential and commercial trade work. The 1\/4-28 fine thread pitch provides tighter thread engagement compared to coarse thread variants, making it a common choice for metal-to-metal joints where vibration resistance or precise torque control matters. Typical applications include control panel assembly, electrical enclosure work, HVAC equipment access covers, and general mechanical assembly in shop or field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 unified fine thread for tight thread engagement in metal applications\u003c\/li\u003e\n\u003cli\u003ePan head profile keeps a low, broad bearing surface without sharp edges\u003c\/li\u003e\n\u003cli\u003eSlotted drive compatible with standard flathead screwdrivers\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n\u003cli\u003eNo washer — fastens directly without an integrated washer flange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 x 1 inch pan head slotted machine screw for general-purpose use in electrical, HVAC, plumbing, and mechanical assembly applications where this thread size and head style are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a flathead screwdriver or slotted bit sized for a 1\/4-inch pan head fastener. Always de-energize electrical equipment before fastening or removing screws on live panels or enclosures, following applicable NEC lockout\/tagout procedures. Do not overtighten into tapped holes in thin sheet metal, as fine threads can strip under excessive torque. Inspect threads and mating holes for damage or debris before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 (Unified Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Pan Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0161 pounds (per piece)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1516MSP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706468073778,"sku":"1516MSP","price":5960.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70d114499d0734c99a652db55d711776.jpg?v=1788434872","url":"https:\/\/voomisupply.com\/products\/value-collection-1516msp-1-4-28x1-pan-head-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
