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.

Crome Acorn Cap Nuts


Metric acorn nuts, Chrome plated class 5.8 steel - Nut size (A.K.A. diameter) is the size bolt that the nut is used with. The same is true of the thread pitch. Thus a 6mm x 1.0 nut fits a 6mm x 1.0 bolt.

Chrome Nuts and Bolts - Chrome fasteners, like our polished chrome nuts and bolts, are the perfect way to add that special something to your car, motorcycle, or boat. Add a professional finish to your project with chrome fasteners from Bolt Depot.

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




Heavy hex nuts, Zinc plated steel - Nut size (A.K.A. diameter) is the size bolt that the nut is used with. The same is true of the thread count. Thus a 1/4"-20 nut fits a 1/4"-20 bolt. Bright zinc plated and clear passivated RS, Professionally Approved Products, gives you professional quality parts across all product categories. Our range has been testified by engineers as giving comparable quality to that of the leading brands without paying a premium price.

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.

Hammer Drive Anchors & Galvanized Carriage Bolts

Hammer Drive Anchors


Use a hammer anchor from Grainger for light-duty or heavy-duty applications. Set hammer anchors with a hammer, inserting or expanding them into predrilled holes in concrete, brick or cement block. You'll also find crimp anchor and anchor rivet styles here. Shop this huge selection by material type, anchor diameter, anchor length, shank length, brand, price or any combination of these specifications. Find the hammer anchor types that fit your applications in the quantities you need at Grainger.

The Hammer-Set one-piece zinc plated steel anchor consists of an expansion body and expander drive pin. Anchors meet or exceed GSA specification A-A-1925A Type 1. (Formerly GSA: FF-S-325 Group V, ?Type 2, Class 3.)

Fast, easy installation.
Works in concrete, block and brick.
Install through material to be fastened.
Low profile mushroom head style.
For use in electric boxes, conduit clips, drywall track and roof flashing.
Not for use in overhead applications.

Sometimes referred to as Zamac Nail in Anchors , they are made from corrosion resistant ZAMAC alloy and can be used in concrete, block, brick or stone. They are quickly and easily hammered into pre-drilled holes.The nail acts as an expansion and locking pin,and they're virtually tamper-proof. The integral unit is made of zinc alloy with hardened steel nail, which is zinc plated per ASTM B633, SC1, Type III. Hammer Drive Anchors ar also available with Stainless Nails.
