1—Carriage bolts have smooth, domed heads with a square section underneath that pulls into the material to prevent spinning during installation.
2—Lag Bolts, or lag screws are large wood screws with hex heads. Typically used for wood construction.
3—Wood Screw- has large threads and a smooth shank for pulling two pieces of material together. Can be used in wood and soft materials.
4—Sheet metal screw- has share points and threads and are design to be driven directly into sheet metal.
5—Hex bolts, or hex cap screws, are used in machinery and construction. Can be used with a nut, or in a tapped hole. Fully threaded hex bolts are also known as tap bolts.
6—Socket screws are machine screws with an internal hex socket (Allen) drive. Longer lengths may have a smooth shank.
7—Machine screws are fully threaded for use with a nut or in a tapped hole. Certain types are some- times referred to as stove bolts.
8Zinc Plated SteelRelatively
inexpensive, with the
zinc plating providing
moderate corrosion
resistance suitable for
indoors or otherwise
dry conditions. Color is
either a blue-ish tint or
yellow depending on the exact process.
9Hot-dipped galvanized steelhas a thicker zinc
coating for better
corrosion resistance,
making it suitable for
outdoor use. Because
of the thick plating,
only galvanized nuts and washers will fit galvanized bolts. The coating typically has a rough, dull grey finish.
10Stainless steeloffers
good corrosion
resistance, making it
suitable for outdoor
use and marine
applications, but is
more expensive than zinc plated
11Chrome and nickel plated steelare
smooth and polished
for appearance. The
plating offers moderate corrosion resistance.
12Brass and bronzeare copper alloys with good corrosion resistance. More expensive than steel, these materials are typically used for decorative applications. Colors can vary significantly.
13Alloy steelIs highly hardened and usually black oxide and/or oil coated, offering little corrosion resistance.
14—Plow Bolts
Similar to carriage bolts but used for attaching the cutting edge of a plow to the plow blade.
15—Eye Bolts
A bolt with a circular ring on the head end. Used for attaching a rope or chain.
16—Eye Lags
Similar to an eye bolt but with wood threads instead of machine thread.
17—Phillips and Slotted drives are common in screws, but prone to cam-out (stripping).
18—Frearson and Pozidriv are similar to Phillips, but less prone to cam-out.
19—Hex socket (Allen)
drives are compact and easy to drive, but prone to cam-out
20—Star and Square drive are resistant to cam-out and can be installed single- handed.
21—Hex heads are typically used with larger bolts and screws, and tightened with a wrench.
22—Oval heads are a low domed and countersunk heads, used primarily for decorative purposes.
23—Flat heads are installed in a countersunk hole for a flat surface.
24—Round heads are tall domed heads, used primarily for decorative purposes.
25—Pan heads have a slightly domed head that sits above the surface.
26—Truss heads are slightly domed, with a wide head for an extra large surface area
27—Socket heads are narrow with a socket drive, and knurled or smooth sides.
28—Button heads feature a medium dome. Typically used with a hex socket drive.
29—U-Bolts
Bolts in U shape for attaching to pipe or other round surfaces. Also available with a square bend.
30—Rivets
Used to join sheets of metal. During installation the rivet body is deformed to perma- nently lock in place. Blind rivets can be installed without access to the back side of the material.
31—Cotter or split pins have two tines which are bent apart to hold them in place.
32—Sex bolts (a.k.a. barrel nuts or Chicago bolts) have a female thread and are used for through bolting applications where a head is desired on both sides of the joint.
33—Mating Screws
Mating screws have a shoulder that matches the diameter of the sex bolts they are used with.
34—Hanger Bolts
Hanger bolts have wood thread on one end and machine thread on the other end
35—Set Screws
Machine screws with no head for screwing all the way into threaded holes.
36—Timber Bolts
Machine threaded fasteners with a wide domed head. The head has fins underneath that prevent the bolt from spinning during installation. Typically used in wood.
37—Spring Toggle Wings
Non-removable fasteners that expand behind the material, e.g. inside a wall, for a secure grip.
38—Stud Anchors A.k.a. Wedge Anchors. One piece expansion bolts for heavy duty fastening into stone or solid concrete.
39—Sleeve Anchors
Heavy duty masonry anchors. Does not require a solid base material for installation.
40—Lag Shields
Medium dury anchors for use in concrete, brick or mortar. Use with a lag bolt.
41—Machine Screw Anchors
A two-piece machine thread anchor for use in stone, brick, or concrete.
42—Double Expansion Sleeves
Expansion anchor for masonry that ensures contact along the length of the hole.
43—Drop-in Anchors
A heavy duty machine thread anchor for concrete or stone
44—Concrete Screws
Used in concrete, brick or block. A quick and easy way to fasten in light to medium duty applications
45—Kaptoggle®
A non removable anchor commonly used for hollow spaces such as drywall and masonry block.
46—Plastic Toggle
When these anchors are driven in they expand inside the hole for a secure grip. Drill hole the same size as the anchor. Non-removable.
47—Hollow Wall Anchors
A.k.a. Molly Bolts. Used for light duty anchoring in drywall or other hollow walls.
48—Wood Screw Anchors
This anchor is made of lead and can be used with wood screws or sheet metal screws.
49—Nail Drive Anchors
Non removable anchors that expand inside the hole when the nail like pin is driven
50—Self Drilling Drywall
Anchors
Quick-install plastic anchors used in drywall with sheet metal screws
51—Anchor Bolts
L shaped, machine threaded anchors. Typically embedded in concrete when it is poured.
52—Conical Anchors
Plastic anchors used with sheet metal screws. Can be used in most materials.
