Bolt Assortment Kits (15)
Miscellaneous groupings of bolts and cap screws to provide a wide range of products for varying applications or industries.
Cap Screws & Hex Bolts (10,061)
Hex Cap Screws feature a washer face under the head and a chamfered point that aids insertion into a tapped hole or nut. Hex Bolts are available in a variety of grades and finishes.
Carriage Bolts (1,139)
These screws have a square neck that resists turning when nut is tightened or removed. Ideal for wood-to-wood and many wood-to-metal applications, such as docks, swing sets and decks.
Coil Bolts (15)
The large, round threads of coil bolts are designed to mate with wire coils used to tie concrete forms together.
Connector Bolts (10)
These bolts have a thin, wide head, and typically an internal hex drive. Often used to join wood together in cabinetry and knock-down furniture.
Elevator Bolts (81)
Elevator Bolts have a square neck which resists turning when the nut is tightened or removed, and a large head which provides a greater bearing surface for soft materials. Used often in conveyor systems.
Eye Bolts (95)
These bolts are commonly used to attach cables. They can be used in various materials such as wood or steel, depending on the type of eye bolt.
Ferry Cap Screws (263)
Also called 12 Point Flange Screws because of the 12-point head and flanged bearing surface. Can be installed and removed with a standard 12-point socket or pneumatic wrench.
Flange Bolts (267)
The built-in washer under the head of a Flange Bolt acts to distribute the clamping load over a greater area. Available in Hex Head and Hex Head Serrated styles.
Hanger Bolts (101)
Hanger bolts are ideal for overhead applications, such as suspending electrical wiring or sheet metal from wooden structures. One end has a wood screw thread and the other end is threaded to hold a nut.
Heavy Hex Bolts (229)
Heavy Hex Bolts have a wider head than that of a standard hex bolt. The large head offers a greater bearing surface that distributes the clamping load over a greater area.
Penta Bolts (20)
A five sided "Pentagon" headed bolt. Used as a tamperproof screw since most standard sockets and wrenches will not work on it.
Plow Bolts (172)
These bolts are excellent for use on road graders, snowplows and similar heavy equipment. They have a countersunk head and a square neck to prevent turning when nut is tightened or removed.
Shaker Screen Bolts (108)
Stronger than a carriage bolt, these self-anchoring bolts have a square neck that resists turning when nut is tightened or removed. Ideal for wood-to-wood and many wood-to-metal applications.
Sidewalk Bolts (3)
This Sidewalk Bolt is used extensively in the Hurricane Panel and Aluminum Fabrication Industry. Lower profile head than a Truss Head, which is also another hurricane industry standard.
Square Head Bolts (297)
Square Head Bolts offer a large bearing area for positive gripping with an open or adjustable wrench. Length is measured from under the head. Head width or wrench size is measured across the flats.
Step Bolts (20)
Step Bolts are similar to Carriage Bolts in that they both have a square shoulder and a larger bearing surface. Step bolts, however have a larger and lower-profile round head.
Structural Bolts (557)
Structural Bolts are designed to withstand the loads of steel-to-steel structural connections. This specialized heavy hex bolt has a flat, washer-faced bearing surface and a chamfered thread point.
Tap Bolts (671)
Designed to be used in drilled and tapped holes, Tap Bolts have a hex head and are fully threaded. Used in non-critical industrial applications.
Tension Control Bolts (68)
Also called "twist-off" bolts, these bolts have a splined extension that will disconnect when the bolt tension reaches a predetermined value. Used in critical steel work.
Timber Bolts (12)
Timber bolts sometimes called mushroom head bolts or dome head bolts can be used in both marine and treated wood applications due to the heavy galvanization applied to the bolts.
Toggle Bolts (3)
Toggle bolts are an anchoring type product that is used when you are unable to attach a screw to a wall stud or ceiling joist. A toggle bolt will have one or two winged supports attached to a long screw.
U-Bolts (229)
Round bent U-Bolts are used to attach pipes to machines. Square bent U-Bolts are sized for lumber applications. Available in Stainless Steel and Carbon Steel.
