What is a straight surface bolt?

A straight surface bolt is a surface-mounted slide bolt that secures a door, window or cabinet by sliding into a keep or receiver. It is fitted to the face of the door or frame rather than recessed into the edge.

Where are polished chrome surface bolts commonly used?

They are commonly used on internal doors, pairs of doors, bathroom/WC doors (where suitable), cupboards, cabinets, shutters and some window applications where a simple additional bolt is required.

What size surface bolt should I choose?

Common sizes include 100mm (4 inch), 150mm (6 inch) and 200mm (8 inch). Smaller sizes suit cupboards and lighter internal doors, while larger bolts are often chosen for wider or heavier doors and for extra holding strength.

Can a surface bolt be fitted vertically or horizontally?

Yes. Straight surface bolts can usually be installed either vertically or horizontally depending on the application, as long as the bolt throws smoothly into the keep and the fixing surface is sound.

How do I look after polished chrome door bolts?

For best results, wipe with a soft cloth and mild soapy water, then dry. Avoid abrasive cleaners that may dull the chrome finish. Regular cleaning helps maintain the mirror-like shine.

What are polished chrome straight surface bolts used for?

Straight surface bolts are fitted to the face of a door or frame (rather than recessed), making them quick to install and easy to operate. They’re commonly used to:

Secure internal doors (including pairs of doors)
Add privacy/security to bathroom and WC doors (where suitable)
Hold windows, shutters, cupboards and cabinet doors closed
Provide an additional fixing point on utility rooms and storage areas

Why choose a polished chrome finish?

Polished chrome is a popular choice for contemporary interiors thanks to its mirror-like shine and easy-clean surface. It pairs well with modern door furniture and looks especially sharp against white doors, grey tones, glass, and minimalist joinery.

Key benefits and considerations

Pros: fast installation, neat appearance, simple operation, versatile positioning (horizontal or vertical)
Cons: surface-mounted hardware is visible; for higher-security external applications you may prefer heavier-duty security bolts

Choosing the right size

These bolts are commonly available in sizes such as 4" (100mm), 6" (150mm), and 8" (200mm). As a general guide, larger bolts can offer more holding strength and suit wider doors, while smaller sizes are ideal for cupboards and lighter internal use.

Fitting guidance

Because they’re surface-fixed, installation is straightforward with basic tools. Position the bolt so it throws cleanly into the keep/receiver, ensuring smooth movement and a secure hold. Many applications allow fitting to timber, and some settings may be suitable for other substrates depending on fixings and door/frame construction.
