Hy-Ko

Hy-Ko house numbers, letters and signs help you identify a home, mark a business or post a farm entrance. Metal and reflective number styles, property signs and reusable stencils give you choices for displaying an address, posting a message or painting a label.

Hy-Ko Products Company LLC is a hardware manufacturer based in Northfield, Ohio. Its history dates to 1949, and Midwest Fastener acquired the company in 2020. Its products include decorative and identification numbers and letters, residential and commercial signs, and driveway markers.

Alongside automotive key blanks, Hy-Ko offers house, door, cabinet and padlock blanks, house numbers and purple no-trespass products; for a spare key, match the blank to the existing key and lock before cutting.

House numbers, letters and address plaques

Hy-Ko offers aluminum, classic metal, reflective plastic, premium metal and floating-mount house numbers. Readability comes before matching the porch hardware. Your address needs contrast against the surface behind it, and reflective characters need approaching light to reach them. Judge the complete address from the approach, with shrubs and parked vehicles clear of the view.

When replacing a missing digit, match its height, shape and finish to the remaining numbers. A matching color can still leave you with a different-looking digit. Compare the replacement with the whole address before mounting it.

Some Hy-Ko address plaques require separate numbers, while the oval plaques include a number-alignment template. Check package contents and lay out the complete address before fastening anything.

Hy-Ko also offers self-adhesive characters. Get the surface clean and dry, then establish your spacing before peeling the backing.

Property signs and painted lettering

Hy-Ko’s sign range includes residential and commercial signs, purple no-trespass products, heavy-duty plastic fence signs, and garage and yard sale signs. Sign materials include corrugated plastic, plastic, Tyvek and aluminum. Work out the support and attachment along with the wording so the message stays facing the approach. At an entrance, place it where someone can read it before passing through.

For painted labels, Hy-Ko offers reusable stencils and water-resistant stencil board. Stencils keep the lettering style consistent across repeated labels. Hold the stencil flat and apply paint lightly so it stays inside the character edges.

Reflectors and driveway markers

Hy-Ko offers reflectors, reflective safety tape and driveway markers, including solar models. Its safety range also includes cones and boundary-marking flags. Start with the point or edge you need someone to see, then position the marker where approaching drivers have a clear view.

Frequently Asked Questions

What is a Hy-Ko key used for?

Hy-Ko offers automotive, house, door, cabinet and padlock key blanks. A blank is the starting piece that’s cut to match a working key, and it needs to fit the lock before cutting. For a car key with a transponder, getting the blade cut is only part of the job; the electronics need to work with your vehicle too.

Are Hy-Ko house numbers reflective?

Hy-Ko offers reflective plastic house numbers, but not every house-number style is reflective. Reflective numbers return light toward its source; they don’t light themselves. If you’re choosing numbers for visibility after dark, check for a reflective description rather than judging by a shiny finish.

Does Hy-Ko offer no-trespassing signs?

Yes, Hy-Ko offers purple no-trespass products, and its property-sign assortment includes heavy-duty plastic fence signs. Choose wording someone can read before entering, and plan the attachment before putting the sign up. A sign that twists away from the approach leaves your message facing the wrong direction.

What products does Hy-Ko offer?

Hy-Ko offers signs, numbers, letters, keys, key accessories and key machines. Its key accessories include key caps, coils and tags. If you’re sorting similar-looking keys, a tag gives you room to identify each one without relying on its shape.
