6-32X5/8 1/4" Across Flats Hex Male Female Standoff Steel Zinc Plated (Pack Qty 250) BC-141006HM by Korpek
Asin: B095VPPZ5N | Model: BC-141006HM | PartNumber: BC-141006HM
It Is Conductive, Resists Corrosion, And Is Non-Magnetic. It Is Costlier And Heavier Than Aluminum And Is Usually Plated Zinc Or Nickel. Stainless Has The Advantages Of Brass But Has Superior Resistance To Corrosion And Chemical Fumes. Steel Is Used For I.
Stainless: Type 303 Stainless Steel: 12L14 Steel-Leaded Grade A (Carbon: .15% Maximum; Manganese: .85-1.15%; Phosphorus: .04-.09%; Sulphur: .26-.35%).
Aluminum: 2011 Aluminum (Copper: 5.0-6.0%; Silicon: 0.4% Maximum; Iron: 0.7% Maximum; Zinc: 0.3% Maximum; Bismuth: 0.2-0.6%; Lead: 0.2-0.6%) Nylon: Nylon 6/6 Brass: C36000 Brass (Copper: 60.00-63.00%; Lead: 2.50-3.70%; Iron: .35% Maximum).
Male-Female Standoffs Are Used When One Of The Components Is Internally Threaded. Aluminum Is Popular For Its Light Weight/ Strength Compromise. It Is Non-Magnetic, Performs Well In Severe Temperatures, And Has Insulating Properties. Nylon Is A Good Insul.
Features
- A hex or round shaped, mechanical device which has an opening with a partial internal thread at one end, and an externally threaded post at the opposite end. It is used to hold two components at a given distance from each other.

Asin: B095VPPVPL | Model: BC-1136MSP | PartNumber: BC-1136MSP
Stainless: 18-8 Stainless Steel Machine Screws Are Used In Applications Which Require General Atmospheric Corrosion Resistance, In Food Processing Machinery And Refrigeration Equipment. Stainless Is Also Superior To Steel In Withstanding Some Elevation I.
Aluminum: In Some Applications, Aluminum Machine Screws Can Be A Less Expensive Alternative To Stainless Screws Because Of Their Resistance To Corrosion And High Rate Of Conductivity. Aluminum Machine Screws Should Be Fastened With Aluminum Nuts To Minimi.
410 Stainless Steel Is Recommended In Applications Where Greater Tensile Strength Is Needed Such As Control Mechanisms Or Valves Under High Stress. 410 Is Not As Corrosion Resistant As Are 18-8 Or 316 Stainless..
Steel: Steel Zinc Is The Most Common And Most Popular Variety Of Steel Machine Screws. Steel Zinc Yellow Screws Are Popular In Electronics Applications. Steel Zinc Black And Black Oxide Screws Are Used To Blend In With Black-Colored Components..
Features
- A straight shank fastener with external threads designed to go through a hole or nut that is pre-tapped to form a mating thread for the screw. Machine screws form a fastening superior in strength to spaced thread screws.

10-12X4 Slotted Indented Hex Washer Self Tapping Screw Type A Fully Threaded Zinc (Pack Qty 500) BC-1064ASW by Korpek
Asin: B095VPPVPH | Model: BC-1064ASW | PartNumber: BC-1064ASW
Steel: Rockwell C45 Minimum.
Steel: Aisi 1016 - 1024 Or Equivalent Steel.
Screws Shall Be Quenched In Liquid And Then Tempered By Reheating To 650°F Minimum.
Features
- For self starting in thin (.015-.050 thick) metal or resin-filled plywood. 18-8 Stainless steel tapping screws may be used in applications which require general atmospheric corrosion resistance. Fastening stainless steel parts to aluminum or steel can cause a type of corrosion known as a galvanic couple in some environments
- Screws shall be quenched in liquid and then tempered by reheating to 650 F minimum
- Steel: Rockwell C45 minimum
- Steel: AISI 1016 - 1024 or equivalent steel
