As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under \"Comments\" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.
Measure Twice, Cut OnceSince custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring TapeExtend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2\" has a bigger mark than 1/4\" which has a bigger mark than 1/8\". The smallest mark follows at 1/16\". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End HookThe sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
G-10/FR4 Glass Epoxy is a high-pressure thermoset laminate known for its extremely high mechanical strength, near-zero moisture absorption, and flame retardant properties. G-10/FR4 is the global standard for electrical insulation in both dry and humid environments. As a direct Garolite equivalent engineered for stability, this FR4-grade material features UL94 V-0 flame retardancy. It is the primary choice for printed circuit boards, terminal boards, and aerospace components where safety and structural integrity are critical. Beyond electronics, G-10 is non-conductive and non-magnetic, making it the industry standard for MRI and medical imaging applications where metal is strictly prohibited. Its ability to maintain high mechanical strength without interfering with sensitive magnetic fields ensures reliability in critical diagnostic environments. Looking for a material with even higher temperature resistance? Explore G-11 Glass Epoxy. For the non-fire rated version, see G-10 Glass Epoxy. G-10/FR4 is favored for its near-zero water absorption and superior dimensional stability. Choose G-10/FR4 for: While the terms are often used interchangeably, the primary difference lies in fire safety requirements. G-10/FR4 is a tough and highly abrasive material that will dull standard high-speed steel (HSS) tooling quickly. It requires carbide tooling for clean machining due to its glass-weave reinforcement. The fine glass dust produced during cutting is a known irritant and requires specialized dust collection. G-10/FR4 (NP510A) complies with MIL-I-24768/27, Type GEE-F and NEMA FR-4 requirements, ensuring it meets the most rigorous military and aerospace standards for structural laminates. Trusted Industry Expertise When you order from Interstate Advanced Materials, you're accessing an expansive nationwide network of material expertise. We source our G-10/FR4 from world-class laminators to ensure every sheet meets precise MIL-spec and NEMA standards, providing the reliability required by engineers in the aerospace and semiconductor industries.
