12-24 Threaded Screw – ICACSS01BK – active 1-1974. The number “12” is a size designator. The number “24” refers to 24 threads per inch. You can identify a 12-24 screw by measuring the diameter with a ruler at slightly less than 7/32″ (slightly larger than 3/16″ or 0.216″).

Hinge holes are drilled at a 35mm diameter, and 12.5mm deep. All hinge holes are drilled to an industry standard: 22mm from the edge of the door to the centre of the hole.

The general rule used to determine the number of hinges is: Every door should be provided with at least one hinge for every 30 inches in height or portion thereof; however, more hinges may be required per chart below. For example, a 90″ door needs three hinges and a 91″ door needs four.

In general, you’ll want to use one hinge for every 30 inches of door height. For example: Use two hinges for doors up to 60 inches tall. Use three hinges if the door is between 60 and 90 inches tall.

The hinge bolts are designed to prevent doors being lifted from their hinges. Manufactured from hardened steel it resists hacksawing. Hinge bolts are essential for all outward opening timber external doors.

To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

Machine screws are often found in sizes of: 0, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14—the larger the number, the larger the screw.

A 6 gauge screw will have a head almost equal to 6 mm wide. … Gauge= (Head diameter in sixteenths of an inch X 2 ) – 2. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8. The above formula means that for imperial gauge, the diameter in mm is almost half the gauge.

Exact threads can vary by manufacturer. The number “10” is a size designator with no numerical meaning. The number “32” refers to 32 threads per inch. You can identify a 10-32 screw by measuring the diameter at exactly 3/16″ (4.76 mm).

A #8 screw size is . 164 fraction of an inch. The diameters listed in the chart below are in fractions of an inch, so the #12 is just shy of 1/4 inch.

8-32: 0.1640 or 41/250 in diameter; 32 threads per inch.

Larger gauge numbers indicate screws with thicker shafts. While utility screws are typically #8 or #10 gauge, steel wood screws are available in a much wider selection of gauge diameters.

#14 is close to, but not exactly the same as, 1/4-inch.) The major diameter in Unified threads = 0.060″ + 0.013″ x (numbered diameter). So #2 has a major diameter of 0.086″. … We see that #14 would be 0.242 inches and #1/4 is 0.250 inches.
