Description
Traditional Elegance Meets Dependable Physical Security
Finding the right architectural hardware often means balancing classic aesthetic charm with uncompromised daily security. Standard light-duty barrel bolts frequently suffer from loose, rattling barrels, flimsy shoot mechanisms, and premature mechanical wear. Over time, poorly constructed bolts drop out of alignment, causing friction against door frames and leaving properties vulnerable or awkward to secure. Timber doors naturally settle and expand with seasonal humidity changes, requiring hardware that offers positive, dependable physical engagement without sticking or slipping loose under pressure.
The AQ82 152mm Surface Bolt Polished Brass solves these common functional frustrations through thoughtful British architectural design. Manufactured from durable solid material with an eye-catching polished brass finish, this surface-mounted door fitting combines traditional elegance with heavy-duty construction. Unlike lightweight round barrel bolts, this hardware features an engineered flat sliding barrel that disperses lateral force evenly across its solid body, delivering a noticeably more robust barrier against forced entry, warping, and vibrational movement.
Whether installed on grand period entryways, heritage interior double doors, or rustic utility spaces, the AQ82 152mm Surface Bolt Polished Brass brings a reassuring weight and tactile quality to any door assembly. Its precision internal ball and spring mechanism ensures that every time you slide the shoot into place, you experience a firm, tactile engagement that stays securely put until you choose to open it again.
Core Features and Mechanical Benefits
Flat Sliding Barrel Security
Traditional round barrel bolts can be susceptible to twisting and leverage under heavy stress. This flat slide bolt profile creates a significantly broader contact surface along the backplate, distributing resistance forces over a wider area. The result is superior resistance to forced movement, giving you greater peace of mind across both domestic and commercial environments.
Positive Ball and Spring Retainer
One of the most persistent nuisances of cheaper door fittings is bolt creep, where gravity or door vibration causes an unlatched bolt to slide downward or an engaged bolt to shake free. The integral ball and spring mechanism holds the bolt firmly in both the extended and retracted positions, ensuring smooth, controlled operation every single time.
Versatile Inward and Outward Striking
Door frames come in a wide variety of configurations, from flush architectural jambs to rebated multi-panel arrangements. To make fitting seamless regardless of your frame design, this unit comes supplied with interchangeable strike plates, enabling easy surface installation on both inward-opening and outward-opening doors.
Ten Year Mechanical Guarantee
Architectural hardware should be an investment that lasts for years, not a component you have to replace after a few seasons. Backed by a comprehensive 10 year mechanical guarantee, this surface bolt reflects rigorous manufacturing quality, dependable moving components, and lasting operational integrity you can trust.
Installation and Operational Pipeline
Stage 1: Pre-Fitting Alignment and Position Marking
Begin by deciding whether the bolt will sit horizontally across meeting stiles or vertically at the top or bottom of the door. Hold the backplate firmly against the timber face, confirming that the 25mm throw reaches sufficiently into your chosen strike plate without binding. Mark the fixing screw locations accurately with a sharp pencil or marking awl to keep everything plumb.
Stage 2: Pilot Drilling and Strike Selection
Always drill small pilot holes before driving fixing screws into hardwood or softwood doors. This protects timber from splitting and avoids shearing brass screw heads during installation. Select the flat plate strike for flush rebated frames or the angled bracket strike for outward swinging doors, aligning it directly on the frame opposite the barrel.
Stage 3: Secure Fixation and Friction Testing
Using the supplied matching screws, fasten the main body to the door leaf, taking care to tighten evenly across the 152mm body. Fasten the strike plate to the frame, ensuring consistent clearance around the bolt head. Slide the shoot back and forth to confirm that the internal ball bearing clicks decisively into place without dragging against the woodwork.
Stage 4: Long-Term Finish Preservation
Polished brass develops its characteristic warmth through gentle, mindful care. To preserve the bright surface sheen, clean the metal exclusively using a soft microfibre cloth dampened with mild soapy water. Alternatively, treat the surface with a quality car wax or natural beeswax to form an invisible protective barrier against fingerprints and atmospheric oxidation.

Essential Maintenance and Care Instructions
Polished brass is a living, premium architectural finish that rewards proper care. To keep your hardware in pristine working order and maintain its radiant appearance, please observe the following care guidelines:
- Clean regularly with a soft cloth lightly moistened with warm, mild soapy water, then buff dry with a clean microfibre cloth.
- Periodically treat the polished surfaces with a thin layer of natural beeswax or a non-abrasive high grade car wax to protect against moisture and tarnish.
- Check fixing screws annually to ensure timber movement has not loosened the backplate.
IMPORTANT NOTICE: Under no circumstances should you use chemical metal polishes, solvent-based aerosol sprays, abrasive cream cleaners, or scouring pads on this product. Harsh chemicals will strip protective surface coatings and lead to irreversible discolouration.
