Square head bolts provide a larger bearing surface for wrench engagement, making them well suited for structural connections, timber framing, and heavy equipment assembly where high torque application or frequent adjustment is expected. This bolt conforms to ANSI\/ASME B18.2.1 dimensional standards, ensuring consistent thread form and head geometry for reliable fitment in standard hardware applications. The coarse UNC thread pattern offers good resistance to cross-threading and works efficiently in lower-strength or softer base materials.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in general industrial, construction, and maintenance applications where a square head profile is specified. Common installation scenarios include wood-to-steel connections, agricultural equipment, conveyor frames, and utility structures. Plumbers, pipefitters, ironworkers, millwrights, and general contractors regularly stock square head bolts for repair and new-construction work. The 1\/2-13 UNC thread mates with standard 1\/2-13 hex nuts, square nuts, or tapped holes meeting the same thread standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e14-inch length under head accommodates thick structural members and stacked assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eSquare head geometry allows pipe wrench or adjustable wrench engagement where socket access is limited\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.2.1 for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard stock fastener for applications requiring 1\/2-13 UNC square head bolts in Grade 2 steel per ANSI\/ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by ironworkers, carpenters, millwrights, or maintenance mechanics using a pipe wrench, adjustable wrench, or square-socket driver. Ensure mating threads and tapped holes are clean and free of debris before installation. Follow applicable structural or equipment manufacturer torque guidelines for Grade 2 fasteners, and verify that the base material and joint design are rated for the load requirements of the application. Do not use impact drivers without confirming the fastener and joint can tolerate the applied torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3525 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: SMBI20500025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709896884530,"sku":"SMBI20500025","price":957.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb887cf5f8213ba47fca1933b5836be6.jpg?v=1788461979","url":"https:\/\/voomisupply.com\/products\/value-collection-smbi20500025-square-head-bolt-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
