1/2-13 bolt meaning

A 1/2-13 tap The same tap handle as before First we look at our handy little chart again, it tells us for a 1/2-13 threaded hole, we need to drill a 27/64" hole. As a decimal this comes out to approximately .422" so we know we will have a clean hole with none of the left over threads from our (.375" outside diameter) 3/8-16 hole to get in our way.

1/2 " 13/16 " No. 4: RoHS (Restriction of Hazardous Substances) RoHS (Restriction of Hazardous Substances) Their high tensile strength means they can be used in demanding, high-stress Also known as pressure bolts, they meet the high-pressure, high-temperature regulations of ASTM A193 and are used to secure pressure tanks

3/8 in.-16 x 1 in. Zinc Plated Hex Bolt (25-Pack) Hex bolts are hexagonal head fasteners with Hex bolts are hexagonal head fasteners with machine threads. They are commonly used for machinery and construction projects, both residential and commercial.

Tap bolts, Zinc plated grade 5 steel, 1/2"-13. A full thread bolt with a six sided head.

These conditions mean rolled threads are suitable for most applications, as they're less expensive, and on average 7% stronger than cut threads. threads, again in millimeters. This is represented by the last number in a metric bolt's designation. For example, a bolt labeled M10 x 1.5 is a metric bolt with a 10 mm diameter and 1.5 mm

Nominal Size and Threads Per In Basic Pitch Dia Section at Minor Dia Tensile Stress Area Nominal Size and Threads Per In In Sq in Sq in 3⁄8 ‑ 16 0.3344 0.0678 0.0775 7⁄16 ‑ 14 0.3911 0.0933 0.1063

UNC stands for unified course pitch threads whereas UNF stands for unified fine pitch threads. UNF threads are distinguished by having fewer threads per distance than UNC threads. While both UNC and UNF bolts are used for fastening, they are often applied in different fields due to their unique advantages. For example, the coarse threads on UNC

ANSI/ASME B1.1 Unified National Thread - UNC Coarse series and UNF Fine series. UNC and UNF - screw threads 1/2" - 13, 13, 0.500, 12.700, 11.15 

plow bolts, lag screws, studs, nuts, rivets and others Most fasteners are covered by specifications that define required mechanical 1/2 - 13.

NC and UNC mean coarse thread. NF and UNF mean fine thread. NS means special thread. Pitch Diameter is the basic dimension of a screw, threaded hole, or a tap 

The Thread Length (E) for Accu Product Code (APC): SEB-1/2-13-9-A2 would be 1.500-1.750 inches, in accordance with the Technical Specification for this type of 

The latter is also commonly referred to as threads per inch (TPI) or thread pitch. We use the TPI to determine the thread's fineness. The number will also tell if a screw can thread through a bolt. To measure screw size, we take its diameter. If the measurement says 1/4-20, it means it has a diameter of 1/4 inch and 20 threads per inch.

High-Strength Grade 8 Steel Flanged Hex Head Screws. Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure over the surface, eliminating the need for a washer.

Answer (1 of 4): Seems like an incomplete spec to me. Normally a metric sized fastener would be a hex head bolt is described Mdd - pp x LL M means metric; dd is the full millimeter diameter of the threaded shank; and pp is the pitch in millimeters; and
