What You'll Learn

PK nails are used in land surveying
PK nails were created by Parker Kaelon (or Parker Krylon, according to another source) and are extremely strong. However, they are now considered old-fashioned and have been replaced by Mag nails, which have a magnet in them so they can be located by metal detectors.
Despite this, some PK nails remain in place from when they were originally used. For example, one person commented on a forum that they had found a PK nail they had set in 1994, and it was still within one one-hundredth of a foot on about six points.

They are thick-shanked nails with an indentation in the middle of their head
PK nails are thick-shanked nails with an indentation in the middle of their head. They were created by Parker Kaelon (or Parker Krylon) and are extremely strong nails that can be pounded into concrete. They are used by land surveyors to mark a position precisely. They are old-fashioned now and have been replaced by Mag nails, which have a magnet in them, allowing metal detectors to locate them more easily.
The PK nail is a type of nail that is used in construction and surveying. It is a thick-shanked nail, meaning that it has a wide diameter relative to its length. This gives it increased strength and makes it less likely to bend or break when being driven into hard materials. The indentation in the middle of the nail's head serves two purposes. Firstly, it provides a space for the hammer to strike the nail without slipping off, making it easier to drive the nail into the ground. Secondly, it creates a recess in the nail head, which can be filled with a coloured material to make the nail more visible and easier to locate.
PK nails are most commonly used in surveying to mark specific points on the ground. When driven into the ground, they provide a permanent and accurate reference point that can be used to establish boundaries, measure distances, and create maps. The strength of PK nails allows them to withstand the forces of nature, such as rain, wind, and soil movement, without shifting or becoming dislodged. This ensures that the marked points remain accurate over time.
In addition to surveying, PK nails can also be used in construction to join wooden beams or to fasten objects to concrete surfaces. Their strength and durability make them ideal for applications where a strong and permanent connection is required. However, as mentioned earlier, PK nails are considered old-fashioned and are being replaced by more modern alternatives, such as Mag nails.
Despite the shift towards newer technologies, PK nails still hold a place in the history of surveying and construction. They represent a time when manual labour and physical markers were relied upon to establish precise measurements and boundaries. Today, they serve as a reminder of the evolution of tools and techniques in these fields, showcasing the ingenuity and resilience of past generations.

PK nails are thick-shanked nails with an indentation in the middle of their heads. They are driven into the ground to mark a position precisely. The nails were created by Parker Krylon, and are designed to be pounded into concrete. They are now considered old-fashioned, and have been replaced by 'Mag' nails, which have a magnet in them, meaning they can be located by metal detectors.

They are now old-fashioned and have been replaced by 'Mag' nails
PK nails, also known as Parker Krylon nails, are thick-shanked nails with an indentation in the middle of their heads. They are driven into concrete or the ground to mark a position precisely. They are now old-fashioned and have been replaced by Mag nails, which have a magnet in them. This means that metal detectors can locate them much farther and much deeper. Additionally, with the advent of portable battery-powered hammer drills, there is no longer a need to pound nails into concrete or blue rock.
