What makes these strike anchors stand out is the combination of a long, reliable embedment and a simple, one-piece installation that’s ideal for masonry projects. 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.
Use cases that benefit from this anchor
- Mounting electrical boxes, lighting fixtures, or conduit clamps to concrete surfaces
- Securing brackets for shelving, handrails, or equipment mounts
- Installing plumbing supports or machinery anchors on concrete floors
- Any heavy-duty fixture requiring reliable load transfer into solid concrete
Why choose Hillman strike anchors for concrete projects
- Durable steel construction with a rounded head for a clean, professional finish
- Long embedment depth enhances holding power in thick or reinforced concrete
- High/low thread design delivers solid grip with controlled installation torque
- All-in-one solution: anchor and screw included, packaged in a convenient 50-piece box

Installation 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. For larger or load-critical installations, verify substrate integrity and consider professional assessment to ensure code compliance and long-term performance.
