The Hy-Ko 4-inch satin black number 1 delivers die-cast zinc construction with pre-drilled mounting holes and included nails. This flush-mount house number measures approximately 3-4 inches wide with a 0.5-inch depth profile, offering contractors a straightforward installation for residential address identification.
Material Quality and Installation
The die-cast zinc construction provides corrosion-resistant metal that handles Montana’s freeze-thaw cycles. That zinc body won’t crack like plastic numbers when temperatures swing from -30°F to 80°F between seasons. With a 4.9 out of 5 star rating across 20 reviews, contractors consistently praise the quality and modern look.
Pre-drilled mounting holes and included nails make installation simple — mount directly through the holes into siding or trim. No template needed for the standard flush-mount version. The 4-inch character height meets visibility requirements while the satin black finish provides high contrast against light-colored siding.
The standard BK-40/1 model sits flush against the mounting surface. For contractors wanting a premium look, the FM-4BK floating mount version creates a 3-D effect and includes a mounting template with posts instead of nails. That floating version eliminates alignment headaches on uneven surfaces.
Design Specifications and Applications
| Specification | Value |
|---|---|
| Character Height | 4 inches |
| Character Width | 3-4 inches (character dependent) |
| Depth | Flush or approx. 0.5 inches (floating) |
| Primary Material | Zinc |
| Finish | Satin Black |
The raised 3-dimensional script design adds depth without creating snow-catching ledges. Weather-resistant construction handles outdoor exposure — critical when numbers face Montana’s UV exposure at elevation plus moisture from spring snowmelt.
Applications span residential house numbering, small business signage, emergency service navigation, and decorative home improvement. The modern style font works equally well on traditional craftsman homes or contemporary builds.
The Bottom Line
At 4.9 stars from users praising the quality, modern look, and easy installation, these numbers deliver what contractors need. The zinc construction outlasts plastic alternatives that crack in temperature swings. Pre-drilled holes speed installation. The satin black finish maintains visibility without glare issues.
Hy-Ko operates as part of Midwest Fastener, providing a one-source solution for fasteners and hardware needs. Their warranty covers defects in material and workmanship with replacement of defective products.
For basic flush-mount installation, the standard BK-40/1 model handles 90% of applications. Spring for the floating mount FM-4BK version when mounting to uneven log siding or when clients want that premium suspended look. Either way, these numbers handle Montana weather while maintaining the visibility emergency services need.
