Confined Space Fan And Blower Accessories

Allegro flat washers or plain washers increase the surface area to distribute the fastener's load while reducing heat and friction during the tightening process in blowers, fans and more. They can also be used as spacers and provide electrical insulation.

Allegro blower grills provide a protective barrier for the fan blades in industrial plastic blowers & standard blowers by deflecting debris and objects from being inserted into the blades. These grills also reduce the risk of injuries by preventing accidental contact with spinning blades. Choose from a wide range of these blower grills, available in diameters ranging from 8 to 20 inches.

Allegro blower grommets are used for covering the sharp and rough edges of holes present in the blower. They are compatible with numerous Allegro blowers, including 9513, 9513-05, 9515, 9525, 9530, 9515, 9516, 9525, 9525-50, 9530, 9513 and 9513-05 models.

Allegro tap bolts or hex head bolts feature hex headed bolts with a fully threaded shank for use in a variety of projects including attaching motors to machinery, marine and exterior woodworking applications. They are inserted through drilled holes in assembled parts and tightened by torquing a nut They can also be mated with an internally threaded (tapped) hole and tightened by torquing the bolt's head. Tap bolts have high tensile strength for withstanding harsh or corrosive environments.

Allegro hex nuts are designed for fastening components together in Deluxe dewatering pumps used for removing / extracting water in mining & basement drainages. Their 304 stainless steel construction prevents highly abrasive environments from damaging / wearing the fastener.

Allegro lock washers or external tooth lock washers are a special type of washers that create tension so that the bolt doesn't loosen or come out of its installed position. Lock washers comes in semi-coiled shape or have teeth protruding away from their outer diameter. They prevent the rotational movement of the installed bolts by locking them in place. These washers unlike nuts, do not get loose when exposed to vibrations.

Allegro machine screws are ideal for fastening metal parts securely together in various types of machinery or construction applications. They convert torque (rotational force) to linear force and are one of the six classical simple machines. These metal screws clamp machine parts together, either in conjunction with a nut or when one of the parts has a threaded hole.

Allegro manhole signs remind workers to follow proper confined space procedures meeting OSHA's confined space warning requirements. They are made of high impact polycarbonate and fit under the manhole cover. These manhole signs feature ventilation holes that allow air to pass through and water to drain in. The design offers ease of using instrument probes without having to remove the sign from its position under the manhole cover.
