Bolt-On Winches

Bolt-On Winches

Bolt-on winches give flatbed and trailer operators a way to add a 4" strap winch without welding and without a track system. They are held in place with screws and can be removed and repositioned when the load layout changes. Fasteners Plus carries two steel bolt-on winches, a standard bottom mount and a low profile side mount, both with a 5,500 lb. working load limit for 4" winch straps.

Standard Bolt-On Winch

The 4" Standard Bolt-On Flatbed Winch is a bottom mount design in black painted steel, built to work with 4" wide tie-down straps. It carries a 5,500 lb. working load limit and a 16,500 lb. assembly break strength, and its page lists storage for up to 20' of 4" webbing. It measures 7.71" wide, 3.54" long, and 5.51" high, weighs 8.35 lbs., and includes mounting screws. It is aimed at flatbeds, trailers, and utility vehicles that need heavy-duty cargo securement without a permanent weld-on winch.

Low Profile Bolt-On Winch

The 4" Low Profile Bolt-On Flatbed Winch is a side mount winch for applications where clearance is limited. It has the same 5,500 lb. working load limit and 16,500 lb. assembly break strength in a lower, lighter body: 7.71" wide, 3.93" long, and 4.29" high at 7.4 lbs., with storage for up to 15' of 4" webbing. It is black painted steel, comes with screws, and can be removed and repositioned as needed for flatbeds, utility trailers, and other cargo transport systems.

How to Choose a Bolt-On Winch

• Webbing width: Both bolt-on winches are made for 4" winch straps. Browse winch straps to match the strap to the winch.
• Mount style and clearance: The standard winch is a bottom mount. The low profile winch is a side mount designed for tighter clearance.
• Strap storage: The standard winch stores up to 20' of 4" webbing, and the low profile winch stores up to 15'. Pick the capacity that suits your strap lengths.
• Working load limit: Both winches list a 5,500 lb. working load limit. Work from the working load limit, not the assembly break strength, and match your strap, anchor points, and load to it.
• Bolt-on, weld-on, or sliding: Bolt-on winches are portable and can be repositioned. If you want a permanent fixed winch, look at weld-on winches. If you run C track or double L track, see sliding winches.

The performance of any winch depends on the surface it is attached to and the hardware holding it there. Review the trailer manufacturer's guidance and consult a qualified professional for your equipment, and follow the winch and strap manufacturer's instructions.

Common Applications

• Flatbed trucks and flatbed trailers
• Utility trailers and utility vehicles
• Heavy-duty cargo securement with 4" winch straps
• Loads that change often, where winch position needs to be adjustable

Bolt-On Winch FAQs

What is a bolt-on winch?

A bolt-on winch is a strap winch that is secured with screws or bolts, not welded, so it can be removed or moved to a different position on the flatbed or trailer.

What is the difference between a bolt-on winch and a weld-on winch?

A bolt-on winch is portable and repositionable, while a weld-on winch is a fixed, permanent attachment. Sliding winches ride in a C track or double L track so they can be moved along the trailer.

What size strap do bolt-on winches use?

Both bolt-on winches in this collection are designed for 4" wide winch straps.

What is the working load limit of these winches?

Both list a 5,500 lb. working load limit and a 16,500 lb. assembly break strength. The working load limit is the figure to plan around.
