Chain bolt. Also found in: Encyclopedia. (Naut.) The bolt at the lower end of the chain plate, which fastens it to the vessel's side. A bolt with a chain attached for drawing it out of position.
What is a chain bolt used for?
Chain bolt provides a method of securing a gate or door in the open (or closed) position. The bolt is made of 5/8" square steel. It is spring loaded and it is beveled on the latching end. The bevel allows thebolt to automatically retract and then lock when the bolt hits the strike. The strike is also beveled to help the bolt retract.
What is the best chain bolt for a chainsaw chain?
This chain bolt would be best where you need a heavy duty safety mechanism, where aesthetics are not as important. It's definitely heavy duty, built for a specific application. Seed Program Review (What's this?) The EVERBILT 6 IN. ZINC PLATED CHAIN BOLT is well made and hopefully will no rust over time. I us... The EVERBILT 6 IN.
What is the size of the chain bolt on the gate?
An 18" chain is attached. The chain is used to release the bolt from the strike, thereby freeing the gate or door. Dimensions of chain bolt: Throw of bolt is 7/8".
Is there a chain that can't be cut with bolt cutters?
Is there a chain that can't be cut with bolt cutters? The short answer is yes, you can get cut-resistant chain. It's hardened throughout its thickness, and its flat face distributes the force of the bolt cutter's jaw over a wide area, thereby diffusing it. There are also industrial high-strength welded steel chains that are through-hardened.
What is a chain bolt used for?

What is chain bolt construction?
Definition of chain bolt : a bolt with a chain attached for drawing it out.
What is a foot bolt?
: a bolt operated by foot pressure and attached to the bottom of a door to hold it in either open or closed position.
What is a flush bolt?
Flush bolts are used to secure the inactive leaf of a pair of doors, projecting into the frame head and into a floor strike. In this application, the active leaf would typically have a lockset which latches into a strike mounted on the edge of the inactive leaf.
What is barrel bolt?
Definition of barrel bolt : a door or sash bolt made to slide into a cylindrical socket.
How do you use a foot bolt?
Foot bolts can be used on right or left-hand applications, on in-swinging and out-swinging doors, and are locked by applying the pressure of your foot to the cap and unlocked by applying pressure to the spring-loaded tip.
Machine Screw-Style Hangers
Also known as spade bolts, you can use these versatile hangers in a threaded hole (as you would a screw), or secure them with a nut (as you would a bolt). Zinc plating provides corrosion resistance in wet environments. Material meets ASTM A307 or F2282 specifications for quality.
Chain-Grip Spring-Loaded Slide-Bolt Latches
Pull the chain-grip to unlatch hard-to-reach doors and panels. Bolts are spring-loaded to stay latched until you activate the pull. All latches have bolts that can be rotated 180°, so they can be used with both push and pull doors. They are reversible for right- and left-hand mounting.
What is a bolt type shackle?
Bolt type shackles can be used in any application that uses a round pin or a screw pin. These types of shackles remain secure even when the shackle is subjected to rotation or torque. Bolt type shackles are practical in many rigging applications where the anchor bolt is expected to experience some rotation. The tightening nut and the cotter pin ...
Why are chain shackles not side loaded?
Chain shackles, also referred to as D shackles, have a D-shaped bow that is narrower than anchor shackles. Because these shackles are designed and rated for in-line tension, they should not be side loaded, as side loading can twist or bend the bow of the shackle.
What is a cotter pin?
A cotter pin is used to secure the shackle pin in place. However, round pin shackles are not recommended for overhead lifting applications. Round pin shackles shouldn’t be used as a collector ring in rigging applications where multiple sling legs are present, or where side loading may occur.
What is a screw pin shackle?
Screw pin shackles are quick and easy to connect and disconnect so they’re convenient for rigging that is used for “pick and place” applications or when slings and other hardware are often changed out. Screw pin shackles are not recommended for permanent or long-term installations.
Why is the bow of the shackle widened?
On a synthetic sling shackle, the bow of the shackle is widened to increase synthetic web sling or synthetic roundsling efficiency. This design allows for 100% of the sling’s WLL to be achieved by preventing the slings from pinching or bunching, which can damage the slings or reduce their rated capacity.
What is a shackle?
A shackle is a u-shaped, load-bearing connecting device designed to be used with a removable pin. Shackles can be used in a number of different rigging and load securement applications to connect different types of lifting slings, chain, or rope to an object or to each other.
What is the part of the shackle that supports the shackle pin?
Ears – portion of the shackle body that support the shackle pin. Pin – a steel bolt made to span the two shackle ears. Shoulder – the part of the pin that makes contact against the ear when the pin is fully threaded or engaged.
What size chain is hard to cut?
The larger diameters of these chains, especially the 5/8-, ¾-, and 7/8-inch size s, are extremely difficult to cut due to their girth and hardness.
What do you need to secure a chain?
You might also have to attach the chain to something secure, such as a concrete footing. Likewise, hasps, bars, and bolts have to be thick and impregnable. It doesn't take much to deter a lazy thief, but it takes a lot to keep out one who's determined to get in, if for no other reason than to prove his point. Any weak link (if you'll excuse the pun) invites trouble in the form of a bolt cutter, an oversize crowbar, ordon't laugha chain hooked to a large pickup truck. I had a neighbor whose home was burglarized by a thief who used the rear bumper of his pickup truck as a battering ram, which he put through the front door.
Can you cut a chain?
The short answer is yes , you can get cut-resistant chain. It's hardened throughout its thickness, and its flat face distributes the force of the bolt cutter's jaw over a wide area, thereby diffusing it. There are also industrial high-strength welded steel chains that are through-hardened. The larger diameters of these chains, especially the 5/8-, ¾-, and 7/8-inch sizes, are extremely difficult to cut due to their girth and hardness. (Note I say difficult, not impossible; there are industrial bolt cutters that have jaw sizes as large as ¾ inch and are designed to cut hardened steel.) Industrial chain is rated by grades; the higher the grade number, the more steel alloying elements it contains and the more resistant it is to the variety of loads a chain encounters, especially in tension. Grades 70, 80, and 100 are among the hardest and toughest available. Here's the kicker, though. We're talking chain that costs $10 to $22 per foot; it's likely to be more valuable than what you're chaining down, a fact that might not be lost on an enterprising thief, who might just make off with the chain itself!
