The 700040 is a RaceQuip 3 inch snap hook belt end designed as a replacement or upgrade hardware component for 3 inch racing harness systems. Built from forged SAE 1050 steel with a zinc plated finish, this snap hook belt end delivers reliable attachment at the seat belt anchor point. The universal design fits any standard 3 inch racing harness webbing, making it a straightforward solution for drivers building, replacing, or reconfiguring their restraint system hardware.
Construction and Materials
The snap hook body is forged from SAE 1050 steel, a medium-carbon steel alloy known for its high tensile strength and toughness under load. Forging, as opposed to casting, aligns the grain structure of the steel, producing a part that resists cracking and deformation under the stress of racing restraint applications. The zinc plating provides a corrosion-resistant barrier that protects the steel substrate from moisture and oxidation in demanding garage and racing environments. The overall assembled length is 3.80 inches and the width matches the 3 inch belt width it is designed to serve, keeping the hardware compact and low-profile against the seat structure.
Application and Compatibility
This snap hook belt end is a universal fit component intended for use with any 3 inch wide racing harness webbing. It is used at the belt anchor end of a lap belt or sub-strap to create a secure, loop-through connection to a harness eyebolt or floor anchor. Because this is a hardware component only, it does not carry an SFI rating on its own. SFI certification applies to complete assembled harness systems, not to individual hardware pieces sold separately. Racers should verify that their complete harness assembly meets any applicable sanctioning body requirements before competition use.

Frequently Asked Questions
Does the 700040 snap hook belt end carry an SFI rating?
No. This snap hook belt end does not carry an SFI rating on its own. SFI ratings are assigned to complete harness assemblies, not to individual hardware components. If you are competing under a sanctioning body that requires SFI-certified restraints, the full harness assembly must be SFI rated. Consult your series rulebook and harness manufacturer for guidance on building a compliant system.
What harnesses is this snap hook belt end compatible with?
This snap hook belt end is a universal fit component designed for any 3 inch wide racing harness webbing. It is not specific to a single harness brand or model. It works with any belt that uses standard 3 inch webbing and requires a snap hook style anchor end.
How durable is the zinc plating on this snap hook?
The zinc plating serves as a sacrificial corrosion barrier, protecting the forged steel body from rust caused by moisture and humidity. Under normal garage storage and racing use conditions, the plating holds up well. If the part is frequently exposed to standing water, road salt, or harsh chemicals, periodic inspection is recommended. Scratches or chips in the plating over time can expose the base steel, so inspect the hardware before each season or after any significant impact.
How do I install a snap hook belt end on my racing harness?
Feed the loose end of the 3 inch harness webbing through the slot of the snap hook belt end, fold it back over the bar, and route it through the keeper or sew it per the harness manufacturer's instructions. The snap hook end then connects to a floor anchor eyebolt or harness mount point on the vehicle chassis. Always follow the installation instructions provided with your complete harness system and verify the installation before use.
What is the difference between a snap hook belt end and an eyebolt belt end?
A snap hook belt end uses a spring-loaded gate mechanism that clips onto a round eyebolt or anchor ring, allowing for tool-free connect and disconnect. An eyebolt belt end threads directly onto a stud or bolt at the anchor point and requires a wrench for installation or removal. The snap hook style is common for applications where the belt end may need to be detached frequently.
What is SAE 1050 steel and why is it used for this hardware?
SAE 1050 is a medium-carbon steel with approximately 0.50 percent carbon content. It offers a strong balance of tensile strength and ductility, making it well suited for forged hardware that must absorb shock loads without fracturing. The forging process further enhances these properties by compressing and aligning the steel grain structure, resulting in a stronger part compared to a cast equivalent.
Can this snap hook belt end be used on a street car?
This component is intended for racing harness applications and is sold as-is for motorsport use. It is not designed or certified for use with OEM seat belt systems in road-going vehicles. Use on a street vehicle is at the owner's discretion and responsibility. RaceQuip harness hardware is designed for use in dedicated race or off-road vehicles where appropriate seats and roll cages are also present.
What is the weight of this snap hook belt end?
The snap hook belt end weighs 0.2 lbs. The compact 3.80 inch length and low weight help keep the total harness system mass minimal, which is a consideration in weight-sensitive racing builds.
Are there other finish or configuration options for RaceQuip snap hook belt ends?
Yes. The RQP700030 offers the same snap hook style in a black finish for those who prefer a darker look or need to match black-hardware harness builds. For applications requiring a fixed threaded mount rather than a clip-style connection, the RQP700050 and RQP700060 eyebolt belt ends are available. The RQP700075 provides a 3-bar slide style end for adjustable-length belt configurations.
