Milwaukee Packout Under Mount with Hidden Fasteners - 14-Gauge Steel | Low-Profile

The Sleekest Mounting Solution for Tight Spaces and Custom Racks

Stop compromising your build's aesthetics with bulky, exposed hardware. The BOCO Custom Hidden Fastener Single Mount is specifically engineered for high-visibility or tight-clearance applications like motorcycle racks, off-road vehicle consoles, and custom tool walls. Precision laser-cut from 14-gauge American steel, this mount provides a completely flush top surface, allowing your Milwaukee Packout boxes to sit lower and look cleaner than any other option on the market.

Designed for Custom Fabrication

• Hidden Fastener System: Features integrated mounting points that hide your hardware underneath the plate, providing a professional, "factory-installed" look for motorcycles and luxury van builds.
• Motorcycle & Off-Road Ready: The ultra-slim height and steel construction make this the go-to choice for mounting Packout coolers or compact toolboxes to UTV racks and bike tails.
• Ready to Paint or Weld: Ships in Raw Steel (deburred), making it perfect for fabricators who want to weld the mount directly to a chassis or paint it to match a custom vehicle color.
• Precision Fit: Laser-cut to exact tolerances to ensure your half-width Packout gear clicks in securely with zero rattle, even on rough trails.

INSTALLATION TIP: This mount is ideal for "blind" mounting where you have access to the underside of your mounting surface. For standard wall mounting where you need front-facing screws, check out our Standard 14-Gauge Single Mount

10-Gauge Steel (0.1345" | Thickness of Two Stacked Dimes)

• Best For: Heavy-duty commercial wall mounts, shop workbenches, and massive modular tool stacks.
• The Advantage: Extreme structural stiffness. This ultra-thick steel completely eliminates flexing, twisting, and tool rattling, making it the definitive choice for demanding daily job-site use.

12-Gauge Steel (0.1046" | Thickness of a Standard House Key)

• Best For: Mobile service vans, enclosed trailers, and standard shop organization layouts.
• The Advantage: The ultimate sweet spot between bulletproof strength and smart weight distribution. It handles constant over-the-road vibrations flawlessly without adding unnecessary bulk to your mobile rig.

14-Gauge Steel (0.0747" | Thickness of a Nickel)

• Best For: Handheld battery organizers, small tool holsters, and lightweight shelf accessories.
• The Advantage: High-tensile rigidity in a streamlined profile. It provides a rock-solid, permanent mount for smaller gear while keeping your workspace layout clean and low-profile.

8-Gauge Aluminum (0.1285" | Heavy-Duty Marine Grade)

• Best For: Open truck beds, roof racks, exterior trailer sides, and high-moisture environments.
• The Advantage: Maximum corrosion resistance with severe weight savings. Shaved pounds keep your mobile fuel efficiency optimized while remaining completely immune to rain, snow, and road salt oxidation.

10-Gauge Stainless Steel (0.1345" | Thickness of Two Stacked Dimes)

• Best For: Premium exposed truck bed brackets, marine applications, high-end shop builds, and ultimate weather protection.
• The Advantage: Combines the absolute, unyielding structural rigidity of our thickest 10-gauge plate with total lifetime corrosion resistance. It requires no paint or powder coat to stay 100% immune to rust, road salt, and harsh outdoor elements.

Note: Sheet metal gauge numbers run inversely—the lower the gauge number, the thicker and more rigid the actual metal substrate is.

We fabricate our mounting solutions and accessories using commercial-grade materials built for harsh environments. Choose the right finish for your build and review our care recommendations below:

Powder Coat Finish

• What it is: An industrial-grade, chip-resistant finish applied over media-blasted metal. Ready to install out of the box and engineered to survive heavy daily tool friction.
• Care: Low maintenance. Wipe down occasionally with a damp microfiber cloth to remove dust or workspace grime. Avoid using harsh chemical solvents or abrasive pads that could scratch the protective coating.

Raw Steel (Uncoated)

• What it is: Shipped as premium raw American steel that has been completely precision laser-cut, sanded, and deburred. Perfect for fabrication shops or DIYers who want to weld the brackets directly to a rig or custom paint them.
• Care: Requires immediate protection. Apply a clear coat or paint immediately after receiving to prevent surface oxidation (rust). Once coated, maintain with occasional wipe-downs using a dry cloth.

Painted Finish

• What it is: A clean, cost-effective protective coating applied in-house. Perfect for everyday indoor workspace use or setups that won't see extreme, heavy-duty metal-on-metal abrasion.
• Care: Moderate maintenance. Clean with a soft, damp cloth. Avoid harsh chemical solvents, degreasers, or abrasive scrubbing pads, as these can wear down or dull the paint over time. Minor touch-ups can easily be done with standard matching automotive or metal spray paint if scratched.

Aluminum (Uncoated)

• What it is: Premium, lightweight raw American aluminum that has been precision laser-cut and deburred. It offers excellent natural corrosion resistance without adding unnecessary weight to your mobile rig or vehicle setup.
• Care: Low maintenance. While it won't rust like raw steel, uncoated aluminum will naturally develop a dull patina over time when exposed to the elements. To maintain its bright, metallic shine, occasionally clean it with a dedicated aluminum cleaner or a light scotch-brite pad.

304 Stainless Steel

• What it is: Premium marine-grade stainless steel that is 100% rust-proof for life. Perfect for extreme outdoor environments, saltwater exposure, or applications where zero maintenance is required.
• Care: Virtually maintenance-free. Occasional rinses with fresh water in saltwater environments help maintain the pristine finish. No coating or paint needed—ever.
