{"title":"#4 Diameter Screws","description":"\u003cp data-start=\"50\" data-end=\"494\"\u003eWelcome to the “4-Diameter Screws” collection at Old West Iron. This section organizes our screws by \u003cstrong data-start=\"151\" data-end=\"169\"\u003eshank diameter\u003c\/strong\u003e (also called gauge), so you can select by the thickness of the screw shaft rather than head size. The #4 category represents screws with a moderate-shaft diameter — useful for light- to medium-duty woodworking, trim, and furniture projects where a #3 would be too small and heavier gauges (#6, #8, etc.) would be overkill.\u003c\/p\u003e\n\u003chr data-start=\"496\" data-end=\"499\"\u003e\n\u003ch2 data-start=\"501\" data-end=\"507\"\u003eFAQ\u003c\/h2\u003e\n\u003cp data-start=\"509\" data-end=\"791\"\u003e\u003cstrong data-start=\"509\" data-end=\"565\"\u003eQ: What does “#4” mean when referring to screw size?\u003c\/strong\u003e\u003cbr data-start=\"565\" data-end=\"568\"\u003eA: The “#4” is the gauge of the screw — it refers to the diameter of the screw’s shank (the shaft), not the head. In imperial-gauge sizing, the gauge indicates how thick the screw is. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"793\" data-end=\"1178\"\u003e\u003cstrong data-start=\"793\" data-end=\"864\"\u003eQ: Why is the screw grouped by shank diameter instead of head size?\u003c\/strong\u003e\u003cbr data-start=\"864\" data-end=\"867\"\u003eA: Because for structural and functional purposes — strength, pilot-hole size, and how the screw interacts with the material — the shank (or outside thread diameter) is the critical dimension. Head size affects only appearance or how the screw sits in or on the material.\u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1180\" data-end=\"1438\"\u003e\u003cstrong data-start=\"1180\" data-end=\"1219\"\u003eQ: When should I choose a #4 screw?\u003c\/strong\u003e\u003cbr data-start=\"1219\" data-end=\"1222\"\u003eA: A #4 screw works well for lighter tasks where you don’t need great structural strength — for instance attaching trim, hardware, or light cabinetry, or whenever you want a smaller hole and less wood displacement.\u003c\/p\u003e\n\u003cp data-start=\"1440\" data-end=\"1745\"\u003e\u003cstrong data-start=\"1440\" data-end=\"1502\"\u003eQ: Will I find different head types under the #4 grouping?\u003c\/strong\u003e\u003cbr data-start=\"1502\" data-end=\"1505\"\u003eA: Yes. Because we group by shank diameter, screws under #4 might vary in head style (flat head, round head, decorative head, etc.). Head style affects installation method or appearance, but not the nominal strength or gauge of the screw.\u003c\/p\u003e\n\u003cp data-start=\"1747\" data-end=\"2079\"\u003e\u003cstrong data-start=\"1747\" data-end=\"1841\"\u003eQ: Is there a clear way to know what pilot-hole or clearance hole to drill for a #4 screw?\u003c\/strong\u003e\u003cbr data-start=\"1841\" data-end=\"1844\"\u003eA: Yes — the shank diameter (gauge) informs pilot-hole size. For #4-gauge screws, refer to a screw-size chart or guide that matches the gauge to recommended pilot-hole diameter for your material.\u003c\/p\u003e","products":[{"product_id":"hcs-04-antique-restoration-slotted-bubble-head-screw-4","title":"Set of 10 #4 Antique Restoration Slotted Bubble Head Decorative Screw","description":"\u003cp\u003e\u003cb\u003e#4 Antique Slotted Bubble Head Screw\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThis antique restoration slotted head screw is a replica of the traditional screw used on antique and vintage hardware.
