Copper Pipe Fittings & Safety Respirators

Copper Pipe Fittings


Copper fittings are used in hot and cold water lines in plumbing systems when making connections to copper pipe. There are two basic types of copper pipe or tubing: rigid and flexible. Copper fittings can be used with both types of copper pipe. Rigid pipe is generally installed in new homes and provides a neater installation. Flexible copper pipe is best for repair work since it can be run around obstacles without connections or cuts.



Safety Respirators


Respirators protect the user in two basic ways. The first is by the removal of contaminants from the air. Respirators of this type include particulate respirators, which filter out airborne particles; and "gas masks” which filter out chemicals and gases. Other respirators protect by supplying clean respirable air from another source. Respirators that fall into this category include airline respirators, which use compressed air from a remote source; and self-contained breathing apparatus (SCBA), which include their own air supply.

Zinc Plated Steel Machine Screws & Zinc Plated Lag Bolts

Zinc Plated Lag Bolts



Common finishes for steel are zinc plating and hot dip galvanizing. Zinc, the most popular and least expensive commercial plating, offers moderate corrosion resistance. Hot dip galvanized is a thick coating of zinc that protects against corrosion in harsh environments. Stainless steel, though, is a better choice when corrosion is of concern. Hot dip galvanized and stainless steel are usually recommended if the bolts (less than 1/2" in diameter) will be used with pressure preservative treated wood such as "ACQ" (Alkaline Copper Quaternary)—check local building codes and contact your lumber supplier for recommendations.



Zinc Plated Steel Machine Screws

Blades Cutting Tools & Deck Drywall Screws

Blades Cutting Tools



A blade is that portion of a tool, weapon, or machine with an edge that is designed to cut and/or puncture, stab, slash, chop, slice, thrust, or scrape surfaces or materials. A blade may be made from a flaking stone, such as flint, metal (usually steel), ceramic, or other material.


Deck Drywall Screws



From time to time, people criticize me for using drywall screws in so many of my projects. But I really like drywall screws, and not just because they are cheap. They have a fairly flat head, which I think is less prone to getting pulled through the wood than the wedge-shaped heads of other screws. And they are fairly thin, so they are less likely to split the wood.

Drywall screws were originally invented to hang drywall but are now used by many people as an all-purpose fastener. They can sometimes be used in place of wood screws but they do have their limitations. Vice versa for wood screws. Here is how the ubiquitous drywall screw compares to the wood screw.

Galvanized Carriage Bolts



Carriage bolts, Hot dipped galvanized steel

Carriage bolt diameter is measured on the outside of the threads.

Single Expansion Shields anchors, Double Expansion Shields anchors

The term expansion shield is used to describe a masonry anchor that requires the use of a bolt, lag screw or setting tool to expand the anchor once it is placed in a hole in the base material.   Other than epoxy type and concrete screws, all other concrete fasteners use expansion as a means by which their holding values are derived.  Different types of expansion shields have been developed over the years and all continue to have features and benefits that meet today’s application requirements.

Here is a listing of the different expansion shields’ features and benefits with links to both the technical information and product information.

Single ExpansionShields

Can be used for fastening into rock, concrete, brick, etc. If bolt is removed and replaced, holding power is unaffected. One-piece design, made of zinc alloy, is entirely rust-proof.

Double ExpansionShields

Can be used for fastening into rock, concrete, brick, etc. Eliminates high stress points detrimental in fastening into materials of medium hardness, expands fully and has high gripping power. Ideal for shear loads or where bolt is subject to side pressure or vibration. Does not fracture, and permits fastenings at any length.

Serrated Flange Bolts

Serrated hex flange bolts have a ridge or skirt (flange) around the bolt head that distributes the clamping load when the bolt is tightened. The flange works like a washer. Flange bolts are sometimes called frame bolts.
Armed with teeth-like serrations, serrated flange bolts are one-piece bolts bite into surfaces to resist vibration. This bolt is identifiable by the ridge or surrounding the bolt head, this built-in washer under the head of the Bolt acts to distribute the clamping load over a greater area. A flange bolt is designed to provide the same holding power as a washer.

Grade 5 UNC screws, Grade 5 UNF screws

The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value. The UTS is currently controlled by ASME/ANSI in the United States.
