Available without tooling costs, the knob comes in three sizes: 1.25, 1.50, and 1.75 inches. Davies Molding, Enter 583

Adhesive Tape

Applies at many stages

The GS Series high-strength adhesive tape features a second liner added to its permanent, pressure-sensitive adhesive; this is designed to increase assembly and manufacturing ease. The product, which is available in a thickness of 5 to 50 mils, is engineered for use with wood, metal, glass, rigid composites, hook-and-loop fasteners, extruded polymers, polyethylene, and polypropylene. It has gap-filling properties and also serves as a moisture barrier. MACtac, Enter 584

Captive screws

Matches styling scheme

The Prism Series colored knob captive screws feature a stylized over-molded knob and use a durable UL94-VO rated composite material to add color. The product is hardened for additional torque strength and zinc-plated for increased corrosion resistance. Available in two Imperial thread sizes and multiple installation styles, the screws are designed for a variety of applications, including computers, networking and telecommunications, office equipment, and medical applications.

Cordsets and coupling nuts

Rated for wash down

Picofast cordsets have new hex-shaped, 316 stainless steel coupling nuts with no knurling, allowing for easy cleaning. A world standard M8 thread and able to mate with any quick disconnect, the cordsets reportedly work well in food industry applications and other places that use caustic materials. The cordsets are rated to IP 68 and designed to withstand 1,200 psi wash down with water, detergents, and surfactants. TURCK Inc., Enter 586

Double-faced tape

With permanent and temporary adhesives

At 5-mil with a blue polyethylene liner, the Arclad(R) 8904 double-faced tape is designed for bonding CMP polishing pads to granite or with stainless steel platens used for semiconductor wafer polishing. While the permanent adhesive side is intended to bond aggressively to the polishing pad material, the other side contains a removable adhesive that can be cleanly eliminated from polishing platens after use. Engineered to withstand the shear forces of polishing, the product also provides resistance to water, extreme temperatures, and conventional CMP slurries. Adhesives Research Enter 587
