The 3-1\/2\" overall length ensures you reach solid substrata, while the 1-3\/4\" minimum embedment provides strong pull resistance for heavier fixtures. The included 3.5\" screw means fewer components to source and a faster install, especially when mounting brackets, fixtures, or conduit supports to concrete walls or floors.\u003c\/p\u003e \u003ch3\u003eUse cases that benefit from this anchor\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eMounting electrical boxes, lighting fixtures, or conduit clamps to concrete surfaces\u003c\/li\u003e \u003cli\u003eSecuring brackets for shelving, handrails, or equipment mounts\u003c\/li\u003e \u003cli\u003eInstalling plumbing supports or machinery anchors on concrete floors\u003c\/li\u003e \u003cli\u003eAny heavy-duty fixture requiring reliable load transfer into solid concrete\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy choose Hillman strike anchors for concrete projects\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eDurable steel construction with a rounded head for a clean, professional finish\u003c\/li\u003e \u003cli\u003eLong embedment depth enhances holding power in thick or reinforced concrete\u003c\/li\u003e \u003cli\u003eHigh\/low thread design delivers solid grip with controlled installation torque\u003c\/li\u003e \u003cli\u003eAll-in-one solution: anchor and screw included, packaged in a convenient 50-piece box\u003c\/li\u003e \u003cli\u003ePrecise 3\/8\" drill bit requirement aligns with standard tool setups for quick work\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eInstallation tips for best results: use a magnetic bit or driver to align the screw with the anchor, predrill a clean 3\/8\" hole to the required depth, insert the anchor until fully seated, then drive the screw to snug the fixture securely without over-torquing.
